A car, initially travelling at 81 km h-¹, is travelling down a road when it comes up to a school zone. The driver approaches the school zone and slows. Once the driver has passed the school zone, the driver accelerates again. The acceleration-time graph of the car's 40 s journey is shown below.

A mobile police camera is set up in the school zone to capture any speeding motorists. A
speeding motorist is a motorist that travels through the school zone with a speed greater than
40 km h-¹. Calculate the speed that the car travelled through the school zone to determine if
the car will get a speeding ticket.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9024456b-fffd-4346-b2cf-e0ad6984aa58%2Fa27a9f80-0249-4b88-8413-b05cacc83235%2F1su2cv_processed.png&w=3840&q=75)
