Question

A car accelerates from 2.4m/s to 3.4m/s in 3.6 seconds. What is the change in speed?

a) 0.2m/s
b) 1.0m/s
c) 1.4m/s
d) 3.6m/s

Answer 1

The change in speed of the car is 1.0 m/s.

Step-by-step explanation:

The change in speed of the car can be calculated by subtracting the initial speed from the final speed. In this case, the initial speed is 2.4 m/s and the final speed is 3.4 m/s. So, the change in speed is 3.4 m/s - 2.4 m/s = 1 m/s.

Therefore, the answer is 1.0m/s.
