This is most naturally done with algebra. What unknown quantities are there that you can define as variables? What equations can you write to express the facts of the problem?

To learn the basic set-up process for "uniform rate" exercises, please try

. . .original:

. . . . .rate: r

. . . . .time: t

. . . . .distance: d = rt

. . .faster:

. . . . .rate: r + 5

. . . . .time: t - 4/60

. . . . .distace: rt = (r + 5)(t - 4/60)

. . .slower:

. . . . .rate: r - 5

. . . . .time: [fill this in]

. . . . .distance: [fill this in]

Then solve for the time "t".

If you get stuck, please reply showing all of your work and reasoning, starting from the above. Thank you!
