answer the following motion question.

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.
