Answer: C, E
The graph shows the results of a race between Parin and Andrew. Both boys begin the race at the same time.
To find the rate of race, we find the slope
We pick two points for Andrew
(0,90) and (13,0)
Slope =
We pick two points for Parin
(0,100) and (12,0)
Slope =
Andrew runs the race at the rate of -6.9 yd/s
Parin runs the race at the rate of -8.33 yd/s
So, Parin runs the race at a faster rate than Andrew
Andrew finishes the race at 13 seconds
Parin finished the rate at 12 seconds
So, Andrew finishes the race 1 s after Parin finishes the race.
Yards from finish line for Parin is 100 yds
Parin is given a 10 yd head start and wins the race.
So , Parin runs a longer race than Andrew.
Andrew and Parin started the race at time =0
Both of them started at the same time
