Question 1096096
Autumn runs 5 yards per second (70/14)
Chasity runs 70/16=4.375 yards per second.
Autumn is catching up at 0.625 yards per second (5-4.375)
She is 30 yards behind Chasity.  30/0.625= 48  seconds.In that time, she will run 240 yards.
=======================
========================================
distance=velocity* time
When A catches C, she will have run 30 yards further,since she starts off behind and they will meet.
For A
x+30=5*t, where the units are yards on the left and seconds*yards/seconds on the right.
For C
x=4.375*t, because they both run for the same length of time
x=5t-30
x=4.375 t
Set the two equal to each other, since they are both equal to x
5t-30=4.375t
0.625t=30
t=48 seconds
Autumn runs 5 yards/second, so that is 240 yards.
