First of all you need to work out 20 minutes in hours, this can be done by dividing 20 by 60:
20/60 = 1/3
Then you need to divide 15 by 1/3 to get the final speed:
15 / 1/3 = 45 miles per hour
He will need to be traveling at 45 miles per hour,
Hope this helps! :)
1 hour = 60 mins 1 mile = 60 mins 3/4 = 45 mins. 2/3 = 40 mins. So 45+ 40 = 1 hour and 25 mins.
If the width is 12 and the length is 18, the perimeter of the rectangle is 12 + 12 + 18 + 18, or 60. So yes the perimeter can be 60.
Okay try to round the whole number and see if you can solve that should help you
