Question

Sheila is biking at a constant speed. She travels 54 meters in 9 seconds.

Part A

How many meters per second does Sheila travel?

Part B

How long in seconds would it take Sheila to travel 90 meters at this speed?

Answer 1

6 m/s

15 seconds

Explanation:

Speed = distance / time

54 / 9 = 6 m/s

Given the same speed, we can determine the time she would use to travel

time = distance / speed = 90 / 6 = 15 seconds
