Question

Roberts car travels 600 feet and 20 seconds Larry's motorcycle travels 300 feet 12 seconds which is faster the car or the motorcycle explain show work

find unit rates ?

compare unit rates ?

Answer 1

To work this out use the equation;
Speed = distance / time

First lets work out the speed of Robert's car.
600 / 20 = 30
(Robert's car travels 30feet per second)

Next lets do the same for Larry's motorcycle.
300 / 12 = 25
(Larry's motorcycle travels 25feet per second)

We now see the Robert's car is faster by 5feet per second

Answer 2

Find and compare the unit rates:

Robert: 600 ft / 20 sec = 30 ft/sec

Larry: 300 ft / 12 sec = 25 ft/sec

It's obvious that Robert's ride is faster than Larry's.
