Question

10 seconds into a race, Clara was at the 25 meter mark. At 60 seconds into the race, she was at the 100 meter mark. What was the approximate rate of change in Clara's speed between 10 seconds and 60 seconds?

Answer 1

1.5 m/s

Explanation:

To find the rate of change for two different sets of data, you have to divide the distance and the time to find the speed.

Using the general formula: d = rt, where d=distance, r=rate and t=time,

r = d/t

`(distance)/(time)=(meters)/(second)=(75)/(50)=1.5m/s`
