If you're going 80 miles per hour how long would it take to go 80 miles explain how u got your answer

an hour, 80 miles PER HOUR lets say you were going 25 mph it'd take and hour to go 25 miles, they don't add in "Miles Per Hour" because it sounds nice but because it literally says what it means

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
