Problema Solution
A cheetah ran 300 feet in 2.92 seconds. What was the cheetah's average speed in miles per hour?
Answer provided by our tutors
1 mi = 5280 ft
1 ft = 1/5280 mi
300 ft = 300/5290 mi
300 ft = 30/529 mi
d = 30/529 mi the distance in miles
t = 2.92 sec
1 hour = 3600 sec
1 sec = 1/3600 hr
t = 2.92/3600 hr
v = the average speed
v = d/t
v = (30/529)/(2.92/3600)
v = 69.92 mph
The cheetah's average speed is 69.92 mph.
