Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

Acceleration  =  (change in velocity) / (time for the change) .

They may have had the same change in velocity, but if the changes
happened in different lengths of time, then their accelerations were
not the same.

Answer;

Isla had a different time than Hazel.

Explanation;Acceleration is the rate of change in velocity of a given object or a body in motion. Acceleration is given by;   a = (v-u)/t ; where a is the acceleration, v is the final velocity, u is the initial velocity and t is the time taken in seconds. Therefore; acceleration is given by change in velocity divided by the time taken in seconds.When the change in velocity is the same , while the time taken is different, then it means there will be different acceleration. Thus in this case Isla and Hazel shared similar change in velocity but took different time.
