To learn the general set-up method for "uniform rate" word problems, try

**here**. (Wink)

Then:

. . .car:

. . . . .distance: 200

. . . . .rate: x

. . . . .time: 200/x

. . .train:

. . . . .distance: 200

. . . . .rate: x + 5

. . . . .time: 200/(x + 5)

Translate the given relationship, "(car's time) is (train's time) plus (two more hours)", into an equation.**Solve the rational equation**for the value of "x". Back-solve for the required values.

Remember to put appropriate units on your answer! :D
