Question

laps in 2 minutes. Who is the fastest swimmer?
(A) Tyler
B Jose
(c Kevin
D
They all swim at the same speed.

Answer 1

Kevin swims the fastest.

Explanation:

Tyler:

5 laps to 3 mins. = 1 2/3 (or 10/6) laps to 1 lap

(Do 5 divided by 3 to get 1 2/3 and 3 divided by 3 to get 1)

Jose:

6 laps to 4 mins. =1 1/2 (or 9/6) laps to 1 lap

(Do 6 divided by 4 to get 1 1/2 and 4 divided by 4 to get 1)

Kevin:

4 laps to 2 mins. = 2 laps to 1 min.

(Do 4 divided by 2 to get 2 and 2 divided by 2 to get 1)

Kevin is able to swim 2 laps in 1 min, while Jose is only to swim 1 1/2 of a lap and Tyler is only able to swim 1 2/3 of a lap in 1 min. Kevin has the greatest number of laps, so he's the fastest to swim in 1 min.
