CAR           SPEED      TIME     DISTANCE
A              50        t+2       d
B              70         t        d

t, how much time for B to catchup with A
d, distance traveled when catchup occurs

RT=D rule gives this system of equations:

The first question can use the equating of d.

Use that to find the value for d.
