Answer: Acceleration ≅ 0.067 m/s²

Step-by-step explanation:

First we have to convert speeds to meters per second since time is in seconds.

We have to multiply speeds by 1min/60sec

Beginning speed (70m/min)x(1min/60sec) = 70/60 m/s

Final speed (106m/min)x(1min/60sec) = 106/60 m/s

Acceleration = (Final speed - Beginning speed) ÷ time

Acceleration = (106/60 - 70/60)m/s ÷ 9s

Acceleration = (36/60)m/s ÷ 9s

Acceleration = 36m/60·9s²

Acceleration = 36m/540s²

Acceleration ≅ 0.067 m/s²

Answer: Acceleration ≅ 0.067 m/s²
