Mr. Koskos brought a scooter to DHS so he could zoom around the halls while the building is empty. The scooter can accelerate at a rate of 45 m/s2. If Mr. Koskos started at 13 m/s, how much time did it take for him to shoot up to a final speed of 51 m/s?

Answer:

51m/s - 13m/s= 38m/s

38m/s÷45m/s²= 0/8

Explanation:

First we bring the difference in speeds to religion because this is the formula

Secondary speed - primary speed ÷ time

[tex] \frac{51 - 13} {45} =0.8[/tex]

Because we do not have a definite time, according to the division formula, we accelerate to get the time
