Isla’s change in velocity is 30 m/s over 5 seconds. Hazel has the same change in velocity, but it takes her 10 seconds to achieve it.

Which best explains why they would have different accelerations?

Isla had negative acceleration, and Hazel had positive.
Isla's change in velocity occurred over a shorter time than Hazel's.
Isla had positive acceleration, and Hazel had negative.
Isla went a farther distance than Hazel.

Isla's change in velocity occurred over a shorter time than Hazel's.

Reason: acceleration = Δv/Δt, so with the same Δv (30 m/s) but Δt = 5 s vs 10 s, Isla's acceleration = 6 m/s² while Hazel's = 3 m/s².
