A. 36 B. 37.5 C. 40 D. 80 E. 90 Breakdown and solve  Quote: used fuel at a constant rate of 5 gallons every 2 hours. During this time period, if Car X used exactly 3.75 gallons of fuel, Rate of consumption of fuel is 2.5 gallons/hr No of Hours driven is \(\frac{3.75}{2.5}\) = \(1.5 Hours\)... Quote: During a certain time period, Car X traveled north along a straight road at a constant rate of 1 mile per minute Speed is 60 miles/hr So, Total distance travelled is 60*1.5 = 90 miles... Thus, answer will be (E) 90 Miles..

Time taken by carX= 2*3.75/5= 1.5 Speed of car=60 miles/hr Hence distance covered=90 miles Hence E Sent from my ONEPLUS A3003 using GMAT Club Forum mobile app

Since the car travels 2 hours in 5 Gallons, it travels \(\frac{(3.75 * 2)}{5}\) = 1.5 hours in 3.75 Gallons. In the question stem, it has been given that the car travels at a constant rate of 1 mile/minutes, so in 1.5 hours(90 minutes), the car travels 90 miles(Option E)

During a certain time period, Car X traveled north along a straight road at a constant rate of 1 mile per minute and used fuel at a constant rate of 5 gallons every 2 hours. During this time period, if Car X used exactly 3.75 gallons of fuel, how many miles did Car X travel?Speed = 1 Mile/Min Fuel Consumption Rate = 5 Gallons/2 Hours = 5 Gallons/120 Minutes Total Fuel consumed by car X = 3.75 gallons From total fuel usage we can calculate the time taken by the car, let the total time taken be \(x\) \(x = \frac{3.75 * 120}{5}\) x = 90 minutes \(Speed = \frac{Distance}{Time}\) \(Distance = Speed * Time\) \(Distance = 1 * 90 = 90 Miles\) Hence, Answer is E

A. 36 B. 37.5 C. 40 D. 80 E. 90 1 mile per minute = 60 miles per hour. 5 gallons per 2 hours = 2.5 gallons per hour => Distance travelled per 2.5 gallons = 60 miles 3.75 gallons of fuel = 2.5 + 1.25 => 1.25 is half of 2.5 => Distance travelled in 3.75 gallons of fuel = Distance traveled in 2.5 gallons of fuel + Half the distance travelled in 2.5 gallons of fuel => Distance travelled in 3.75 gallons of fuel = 60 + 30 = 90 miles E is the answer.

A. 36 B. 37.5 C. 40 D. 80 E. 90 5 Gallons every 2 hours > 2.5 Every 1 hour! There 3.75  2.5(60 minutes) +1.25 (30 minutes) Total distance= 1 X90 =90 miles. Please give Kudos if you like my explanation

A. 36 B. 37.5 C. 40 D. 80 E. 90 Since the car has a constant rate of 1 mile per minute, we can let r = the rate of the car in miles per hour and create the following equation: 1/1 = x/60 x = 60 mph Since the car uses 5 gallons of fuel every 2 hours, we can let x = the number of hours driven when the car uses 3.75 gallons of fuel and create the following proportion: 5/2 = 3.75/x 5x = 7.5 x = 1.5 hours We know that the rate of the car is 60 mph and the car has been driven for 1.5 hours; thus, the distance driven is 60 x 1.5 = 90 miles. Alternate Solution: Since the car uses 5 gallons of fuel every 2 hours, or 120 minutes, we can let x = the number of minutes when the car uses 3.75 gallons of fuel and create the following proportion: 5/120 = 3.75/x 5x = 120(3.75) x = 90 So, the car is driven for for 90 minutes. Since it travels 1 mile per minute, it will have traveled 90 miles. Answer: E

In 2 hours fuel used=5 gallons so, in 1 hr=5/2 gallons/hr => 5/2*60=5/120 gallons/min
In 5/120 gallons distance travelled=1 mile So, in 3.75 gallons distance covered=120*3.75/5 => 90 miles
(E)

A. 36 B. 37.5 C. 40 D. 80 E. 90 Given ,
1 mile in 1 minute
So, in 2 hours the car travels 120 miles.
5 gallons for 120 miles
1 gallons for 120/5 miles
3.75 gallons for 120 * 3.75 / 5 miles
120 * 3.75 / 5 = 90 miles. The best answer is B.

A. 36 B. 37.5 C. 40 D. 80 E. 90 we know that the actual consumption of gasoline was 3.75. Now, 5 gallons in 2 hours is like 2.5 gallons in one hour. 3.75 is exactly onehalf (of 2.5) greater than 2.5, so that is going to be 3.75 in 1.5 hours. 1 mile per minute is like 60 miles per hour, so we have 1.5 hours, 60 miles per hour. If we multiply both of these numbers we get 90, and the correct answer choice is E.

A. 36 B. 37.5 C. 40 D. 80 E. 90 5 gallons every 2 hours. We can reduce this to a gallon every 24 minutes. We need to burn 3.75 gallons which is 24+24+24+18 = 90 Answer 90. Option E.

Rate of consumption of fuel is 2.5 gallons/hr No of Hours driven is 3.752.5 3.75 2.5 = 1.5Hours= 90 min
