A car travels 55 miles per hour and a plane travels 15 miles per minute. How far does the car travel when the plane travels 500 miles?

If the plane is travelling at 15 miles per minute, it'll take 500/15 = 100/3 minutes = 100/(60x3) hours = 5/9 hours to cover 500 miles. In that 5/9 hours, the car will travel (5/9) x 55 = 30.556 miles. (I've checked it three times because the numbers look a bit messy for an exercise like this, but I think I've got it right.)
if an airplan travels 15 miles in 2 minutes what is the speed per hour
