Question

Chloe drives from her house to her grandmas house 48 miles away in an hour and 12 minutes. How fast was she driving on average?

Answer 1

Answer:

40 miles per hour

change hours and minutes to hours

12 minutes  = 12 minutes * 1 hr/ 60 minutes = 12/60 hrs

12/60 = 1/5 = .2 hours

1 hours 12 minutes = 1.2 hours

48 miles in 1.2 hours

48/1.2 = 40 miles/hour
