A car traveled 300 meters in 30 seconds. A truck traveled 600 meters in 60 seconds. Which car was faster ?
rewona [7]

Multiply the car by 2: 300 meters x 2 = 600 meters

30 seconds x 2 = 60 seconds.

The car also traveled 600 meters in 60 seconds, so the speed of the vehicles are the same.

No vehicle was faster.
