Question

A jet plane, flying 105 mph faster than a propeller plane, travels 4550 miles in 3 hours less time than the propeller plane takes to fly the same distance. How fast does each plane fly?

Answer 1

`Speed= (distace~travelled)/(time~take) \\\\ \therefore Speed~of~jet= (4550)/(3) \\\\ ~~~~~~~~~~~~~~~~~~~~~= 1516.67~ mph`

So, the jet plane is travelling at 1516.67 mph and the propeller plane is travelling at (1516.67 - 105) = 1411.67 mph
