luisjuan,
I always find these sort of questions have an easier way of solving than the long multiplication!
e.g 15mph = 60/15 = 4 minutes per mile so 8 mins = 2 miles.
95miles in 25 mins, divide both sides by 5: 95/5=19 25/5 =5,
then 60/5 = 12 & 12 *19 = 228.
Simpler than the decimals! Hope this helps.
