How long would it take to travel 30 miles at 45 miles per hour?

Answer 1

You want to travel 30/45 of the distance per hour, or 2/3. So, if you travel 45 miles in 60 minutes, then you travel 30 miles in x minutes. 45/60, or 3/4 =30/x. 30/3=10, so you multiply 4*10=40=x. It would take 40 minutes to travel 30 miles at 45 miles an hour.
