Question

When Cheryl goes mountain climbing, she rests 5 minutes for every 15 minutes that she climbs. If Cheryl’s combined time is 2 hours, how many minutes does she rest?

Answer 1

5 minutes for every 15 minutes

2 hours = 120 mins

5 : 15
120 : x


`5x = 15 * 120 \\ 5x = 1800 \\ x = 360`
Answer: She rested for 360 minutes.

Hope this helps. - M
