If a vehicle can accelerate at a rate of 4.3 km/s squared, how long will it take for its speed to change from 30 km/s to 55 km/s?

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.
