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!
