Question

How long will it take you to ski a distance of 36 miles at a speed of 3 miles per 30 minutes?

Answer 1

`color(green)(6)` hours

Explanation:

`(3" miles")/(30" minutes")=(6" miles")/(60" minutes")=(6" miles")/("hour")`

`36 " miles" xx ("hour")/(6" miles")`

`color(white)("XXX")=color(red)(cancel(color(black)((36)))color(white)("X")^6) color(blue)(cancel(color(black)(" miles") ))xx"hour"/(color(red)(cancel(color(black)(6)) color(blue)(cancel(color(black)(" miles")))))`

`color(white)("XXX")=6 " hours"`
