Question

Jess and Wes used to race each other when they were younger. Jess could cover 8

Answer 1

Answer:

160 meters

Step-by-step explanation:

Let call dj  distance run by  Jess    and   dw  distance run by Wes

By Jess courtesy Wes will be  60 meters ahead of Jess

Let call t the time in which both runners are at the same point, which in fact is when both distances are equal

dj  =  8 m/sec * t        and    dw  =  60  +  5 m/sec * t

Then we make  dj = dw

8*t  =  60 + 5*t

3*t  =  60

t = 20 sec

Now passed 20 sec  dj   =   8 * 20   = 160 m

and   dw = 60 + 5*20   dw  =  160 m
