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)

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..

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

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.
