Speed Trap

In Western Europe, rather than patrol the area for speeding, the governments require that commercial vehicles have a recording speedometer installed. While the engine is running, the speed and time is recorded. The speed recordings are collected by customs officials at various checkpoints throughout Europe. From the speed information the officials can determine if the driver has been on the road too long or if any speed laws have been broken. Appropriate fines are then imposed. The information on the graph below is taken from one of these recording instruments.

Assuming the data is from a single trip on the same road, how far has the truck driven? Explain your method of estimating this.

What is the elapsed time?

What is the average speed for the truck?

If the fine for speeding is 5 ECU for each tenth of an hour of speed in excess of 100 km/h what is the fine for this driver?
