A "rocket car" is launched along a long straight track at t=0s . It moves with constant acceleration a1= 1.2 m/s2 At t= 2.5s , a second car is launched with constant acceleration a2 = 7.2 m/s2

I was able to figure out the first part: At what time does the 2nd car catch up with the first one t = 4.2s

But I can't figure this part out:
How fard down the tack do they meet?


Thank you!!
