We will be using the formula r x t = d (rate x time = distance)

Let t1 = 6 hours(How long Jerry travelled before Molly caught up to him - Jerry had been on the road 2 hours when Molly left and it took her four hours to catch up))
Let t2 = 4 hours (How long Molly travelled before she caught up to Jerry)
Let r1 = Jerry's speed
Let r2 = 54 (Molly's speed)
Set up the equation. Both drivers travelled the same distance so:

Jerry was travelling at 36 mph
