What is the speed of each

Question

A van travels 9 miles per hour faster than a motorcycle. If the van travels 185 miles in the same time it takes the motorcycle to travel 140 miles, then what is the speed of each

Answer 1

V = van speed and M = motorcycle speed

V = M + 9

185/V = 140/M since time = distance/rate

185/(M + 9) = 140/M

185M = 140M + 9*145

45M = 9*145

5M= 145

You solve it from here.
