praveen192 · Accepted Answer

1 hour = 60 mins = 60*60 seconds = 3600 seconds
If 12 miles is covered in 3600 seconds
Miles covered in 10 seconds = (12/3600)*10 = 1/30 miles

1 mile = 5280 feet
1/30 mile = (1/30)*5280 feet = 176 feet

Hence option D is correct

iamdp · Answer

Hi

1 hr = 60*60 sec 3600 sec

In 3600 sec travels = 12 miles

In 10 sec travels =  *10 = 1/30 miles

Now 1/30 miles =  feet = 176 feet

vasili · Answer

12 miles per hour=1/5 miles per minute=5280/5 feet per minute= 5280/300 feet per sec

D=Rate x Time

D= 5280/300 x 10= 176 feet

peachfuzz · Answer

12 mi/1hr * 1 hr/60 min * 1 min/60 sec * 5280 ft/1 mi = 176 ft

Answer: D

PareshGmat · Answer

Answer = D = 176

12 miles = 12 * 5280

1hour = 60 * 60 seconds

Distance travelled in 10 seconds  = \frac{12 * 10 * 5280}{60*60} = 176

KarishmaB · Answer

When working on changing units, it is advisable to do it in a single step with the units to avoid errors:

\frac{12 miles}{1 hour} = \frac{12 * 5280 feet}{60 * 60 secs} = 17.6 feet/sec

So distance traveled in 10 secs is 176 feet.

(12*5280) feets/60*60 seconds * 10 seconds

seconds and seconds will cancel out . Ans. 176 feets (D)

OptimusPrepJanielle · Answer

12 miles = 12 * 5280 = 63360 feet Someone is skateboarding at 63360 feet per hour. In 1 hour (i.e. 3600 seconds), distance travelled is 63360 feet. So, in 10 seconds, distance travelled is (63360 * 10)/3600 = 176 feet Hence option (D). -- Optimus Prep's GMAT On Demand course for only $299 covers all verbal and quant. concepts in detail.

+1 for D. 1 Mile =5280 feet. Distance traveled in 60 minutes=12*5280 feet

23a2012 · Answer

the answer is D

12 Mile/1hour= 12*5280/360=176 feet/sec

Bunuel · Answer

MAGOOSH OFFICIAL SOLUTION: The speed is 12 mph. To change this to feet/second, we need to multiply by (5280 ft/mile), to cancel miles, and to multiply by (1 hour/3600 second) to cancel seconds. rar_img3.png So, in 10 seconds, the skateboarder moves 176 feet. Answer = (D)

aimtoteach · Answer

Clocked 55 sec on this one and got it correct.

Here is how I approached it: 
 1) Convert number to unit in questions stem (i.e feet) 5280 * 12 = 63360

2) Convert 1 hour to unit in question stem (i.e. seconds) 60*60 - 3600

3) Divide --> 63360/60*60 * 10 (as we need to find how many feet does she travel in 10 seconds)  
  Answer: 176 feet

JeffTargetTestPrep · Answer

We are given that a skateboarder has a rate of 12 mph. We need to determine how many feet she travels in 10 seconds. Let’s first convert 10 seconds to hours.

Since there are 3,600 seconds in an hour, 10 seconds = 10/3600 = 1/360 hours.

Since rate x time = distance, the skateboarder can travel 12 x 1/360 = 12/360 = 1/30 miles.

Finally, since 1 mile = 5,280 feet, the skateboarder travels 5,280 x 1/30 = 176 feet.
