Question

Carmen runs each lap in 4 minutes. She will run more than 20 minutes today. What are the possible numbers of laps she will run today

Answer 1

Answer: 5 or more laps

One lap takes 4 minutes and she’s running 20 laps. You can solve this by making a ratio saying 1/4=x/20 and cross multiply. This gives you the equation “20=4x”. Divide both sides by 4 which would give you x=5. Now, take into account that it says she’s running more than 20 minutes so your answer is all integers greater than 5.

Answer 2

Divide it

1 lap = 4 minutes

... lap = 20 minutes

So,

`\sf = (20)/(4) = \green{5 \: lap}`

The right answer is 5 lap
