Question

Trevor is training for a race. He swims 1/2 lap in 4/5 minute. At that rate, how many minutes does it take Trevor to swim each lap?A. 4/10B. 5/8C. 8/5D. 10/4

Answer 1

C. 8/5

Step-by-step explanation:

Trevor swims 1/2 lap in 4/5 minute.

To determine how many minutes it takes Trevor to swim each lap we find the unit rate.

`\begin{gathered} \text{Unit Rate=Number of Minutes}/\text{Number of Laps} \\ =(4)/(5)/(1)/(2) \\ =(4)/(5)*(2)/(1) \\ =(8)/(5)\text{ Minutes per Lap} \end{gathered}`

The correct choice is C.
