Question

During a race, a dragster is 200 m from the finish line when something goes wrong and it stops accelerating. It travels at a constant velocity of 45 m/s for 3 seconds to try to finish the race. How far from the finish line is the dragster after 3 seconds?

Answer 1

Answer

135 m

Explanation:

Speed = 45 m/s, time = 3 second

The formula for the distance is given by

Distance = speed x time = 45 x 3 = 135 m

Answer 2

Answer:

65m

Explanation:

-we know that the dragster is going at a velocity of 45m/s for 3 seconds

So in those 3 seconds, the dragster traveled 135m.

-BUT that's how far they are from the STARTING LINE (not the finish line)

they also mentioned that they were 200m from the finish line, so we subtract the 135m that they traveled from the 200m and we get 65m.
