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

Explanation
To swim 4.2 times the original distance, James needs to swim for 4.2 times the original time. Multiply the original time of 10 minutes by 4.2 to get 42, the correct answer.
