Question

Can anyone help me with some summer homework ;(

Answer 1

Their houses are nine miles away from each other. Mark rides his bike at a rate of twelve miles per hour. Each hour consists of sixty minutes; therefore I would do 60/12 to get five, representing him being able to do one mile in five minutes. Hence, you shall perform 9*5 or nine times five to get the answer of fourty-five minutes.

12 MILES PER HOUR

60 divided by 12 = 5 minutes

ONE MILE PER 5 MINUTES

9 multiplied by 5 = 45 minutes

I hope this helps.
