Accepted Solution
A:
Answer:It will take Mei 32 minutes to finish 20 lapsStep-by-step explanation:* Lets explain how to solve the problem- Mei is competing in a remote-control car race- She can complete 15 laps in 24 minutes- We need to find how long she will take to finish 20 laps if she keeps the same speed∵ Mei can complete 15 laps in 24 minutes- Lets find her unit rate∵ Her unit rate = number of laps ÷ the time of this laps∴ Her unit rate = 15 ÷ 24 = 0.625 lap per minute- Now we can use her unit rate to find the time of any numbers of laps∵ She keeps her rate∵ She will finish 20 laps∵ Time = number of laps ÷ her rate∴ Time = 20 ÷ 0.625∴ Time = 32 minutes* It will take Mei 32 minutes to finish 20 laps
