James can swim 750 yards in

10 minutes. If he swims at the same constant rate, how many minutes will it take him to swim 4.2 times this distance?

Drill 1

Question: 5

Page: 337

Let's apply some logic to this one...

If James travels TWICE the distance (at the same speed), his time will be TWICE as long.

If James travels THREE TIMES the distance (at the same speed), his time will be THREE TIMES as long.

If James travels FOUR TIMES the distance (at the same speed), his time will be FOUR TIMES as long.

If James travels FIVE TIMES the distance (at the same speed), his time will be FIVE TIMES as long.

So, if James travels 4.2 TIMES the distance (at the same speed), his time will be 4.2 TIMES as long.

(4.2)(

10 minutes) = 42 minutes

Answer:

Cheers,

Brent
