Question

A dragster completes a quarter mile, 400 meters, at an average speed of 362 m/s.

What was the dragster's time?

show work.

Answer 1

To find the time it took the dragster to complete a quarter mile, we can use the formula:

time = distance ÷ speed

In this case, the distance is 400 meters and the speed is 362 m/s, so we have:

time = 400 ÷ 362

time = 1.10497237569 seconds

Rounding this to three significant figures gives us:

time = 1.10 seconds

Therefore, the dragster's time to complete a quarter mile at an average speed of 362 m/s was approximately 1.10 seconds.

Answer 2

Answer: 144800 m/s

Step-by-step explanation:

By using the formula of speed = distance/time

speed=distance/time

362=400/t

t=362*400

t=144800 m/s
