1. An airplane travels 720 mi/hr. How far will it travel in 2 hrs?

2. A ball rolls across a floor at 5 meters per sec. How long will it take for the ball to travel 75 meters.

    Ok for number 2: the ball rolls across the floor 5 meters per second. So now you know that every second is 5 meters. You're trying to find how many seconds it will take for the ball to roll across 75 meters. So, what times 5 will equal 75? The answer is 15!

    For number 1: 720 times 2
