given , truck can travel 270 miles in the same time that it takes a car to travel 405 miles
the truck rate is 15 miles per hour slower than the car's
let the cars velocity is 'x'
270 / t = x - 15 and 405 / t = x
now , 270 / 405 = x - 15 / x
15 / x = 1 - 270 / 405
x = 405 * 15 / 135
x = 45 miles per hr . . . . . .
