A car that travels 20 miles in 1/2 hour at constant speed is traveling at the same speed as a car that travels 30 miles in 3/4 h

Vsevolod [243]

It’s because 2/3 of 30 miles in 3/4 hours is the same as 20 miles in 1/2 hour.

Proof:

30/1x2/3
60/3 = 20

3/4x2/3
6/12 = 1/2

Brainliest my answer if this helped you out?
