A car is traveling at 55 mi/hour. What is the cars speed in feet per second
2 answers:
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.
Answer:
<em>80.7 ft/sec </em>
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
