Yes, that is the equation to use. How far have you gotten in applying it?

. . .actual:

. . . . .distance: 280

. . . . .rate: r

. . . . .time: 280/r

. . .possible:

. . . . .distance: 280

. . . . .rate: r + 5

. . . . .time: ..?..

Complete the table. Then note the relation: "(possible time) is (actual time) less (one hour)".

**Translate this** into an equation, and

**solve the rational equation** for the value of "r".

If you get stuck, please reply with a clear listing of your steps and reasoning so far. Thank you!
