Question

mr peel started 7 meters away from the motion detector and 2 seconds later he was 3 meters away from the motion detector. find the average rate of changed or slope in meters per second

Answer 1

He started at 7 meters away, so if after 2 seconds now he is 3 meters away, then he move:

`7-3=4`

So he move 4 meters in 2 seconds so to find the rate we divide the meters into the tiem so:

`r=(4)/(2)=2`
