Problema Solution
A star track runner ran 315 feet in nine seconds. What was his average speed in feet per second?
Answer provided by our tutors
d = 315 ft the distance
t = 9 s the time
v = the average speed
The average speed equals the distance divided by the time:
v = d/t
v = 315/9
v = 35 ft/s
The average speed of the star truck runner is 35 feet per second.
