Answer 2

I guess let's take an example

let's say you drive 70 miles per hour

\[\frac{ 70~miles }{ hour }\]

Answer 3

addition? if someone rode a bike for 4.5 hours and his speed was 12 miles per hour wouldnt you add 4.5 and 12 to get 16.5 or multiplication

Answer 4

well you could. @narissa but multiplication would be the more efficient way.

Answer 5

\[\frac{ 12~miles }{ \cancel\hr }*(\frac{ 4.5~\cancel\hr}{ 1 }) = 54~miles\]

Answer 6

okay thank you

Answer 7

@narissa think about if you wanted to find the total # of miles traveled. like i did above. if say if that person rode for 12 hours. it would take alot more time to keep adding that up. that's why you would multiply.
