Question

A car is traveling at 55 mi/hour. What is the cars speed in feet per second

Answer 1

Answer:

80.7 ft/sec

Step-by-step explanation:

You need two conversion factors:

1 mile = 5280 ft, so (52780 ft)/(1 mile) = 1

1 hour = 3600 seconds, so (1 hour)/(3600 seconds) = 1

55 mi/hour * (5280 ft)/(1 mile) * (1 hour)/(3600 seconds) = 80.6666... ft/sec

Answer: 80.7 ft/sec

Answer 2

Answer:

about 81 feet per second.

Step-by-step explanation:

To convert MPH into feet per second you must first take your MPH (55 in this case) and multiply it by 5,280 and then divide the product of 55*5,280, thus giving you 80.666666 which is presumably rounded off to 81.
