Question

Daniel practiced his new dance moves 30 minutes on Monday and again on Tuesday. At the end of one week, how many minutes would he have practiced?

Answer 1

`60color(white)(i)"minutes"`

Explanation:

If Daniel practiced his new dance moves on Monday and Tuesday for `30` minutes on each day, then he danced for two days. Since you know he danced for `30` minutes for each day, multiply "`30` minutes per day" by "`2` days" to determine the total number of minutes he danced for.

Thus:

`2color(white)(i)"days"xx(30color(white)(i)"minutes")/"day"`

`=2color(white)(i)color(red)cancelcolor(black)("days")xx(30color(white)(i)"minutes")/color(red)cancelcolor(black)("day")`

`=2xx30color(white)(i)"minutes"`

`=color(green)(|bar(ul(color(white)(a/a)60color(white)(i)"minutes"color(white)(a/a)|)))`

`:.`, he would have practiced for `60color(white)(i)"minutes"`.
