Question

Brenda has two remote-controlled race cars painted blue and red, respectively. The blue car traveled 54

feet in 4
seconds. The red car traveled 38
feet in 2
seconds.

Which car was faster and by how muc

Answer 1

The red car was faster than the blue car, by 5.5 ft/s.

Explanation:

To determine which car was faster, we first need to find the speed of each car. The equation for speed is:

speed = distance ÷ time

Using this equation, we can find the speed of both cars.

Blue Car

Distance = 54 feet

Time = 4 seconds

speed = 54 feet/4 seconds = 13.5 ft/s (also read as "13.5 feet per second")

Red Car

Distance = 38 feet

Time = 2 seconds

speed = 38 feet/2 seconds = 19 ft/s (also read as "19 feet per second")

19 ft/s - 13.5 ft/s = 5.5 ft/s

The red car was faster than the blue car, by 5.5 ft/s.
