Question

A swimmer swims 4 laps in 3 minutes. What is the swimmer’s unit rate..? Would you divide 4÷3?

Answer 1

The rate can be calculated below

`rate=\frac{\text{laps}}{\text{time}}=(4)/(3)\text{ laps per minutes}`

1 minutes = 60 seconds

3 minutes = 180 seconds

Therefore,

`\text{rate}=(4)/(180)=(1)/(45)\text{ laps per seconds}`
