Question

Leisurely swimming burns around 350 calories an hour. About how many minutes will it take to burn 150 calories through leisurely swimming?

Answer 1

`"25.7 minutes"`

Explanation:

`"350 calories = 1 hour"`

`"150 calories" = 150 cancel"calories" × "1 hour"/(350 cancel"calories") = 3/7\ "hour"`

`3/7\ "hour" = 3/7 cancel"hour" × "60 minutes"/(1 cancel"hour") = 180/7\ "minutes" = color(blue)(25.7\ "minutes")`
