A vehicle traveling at 40 mph is approximately going how many feet per second?

To convert a speed from miles per hour to feet per second, you can use the conversion factor that 1 mile equals 5280 feet and 1 hour equals 3600 seconds.

First, you can determine how many feet the vehicle travels in one hour at 40 miles per hour. Since there are 5280 feet in a mile, you multiply the speed by the number of feet in a mile:

40 miles/hour × 5280 feet/mile = 211,200 feet/hour.

Next, to find out how many feet that equals per second, you divide the total feet traveled in one hour by the number of seconds in an hour:

211,200 feet/hour ÷ 3600 seconds/hour = 58.67 feet/second.

Thus, rounding to the nearest whole number, a vehicle traveling at 40 mph is approximately going 60 feet per second. This calculation demonstrates that the correct answer is indeed the option that indicates 60 feet per second.
