Question

Consider carefully the following three scenarios, and answer each question using an
appropriate mathematical theorem.

1)

2)

3)

A police officer sees a suspicious car on a highway on-ramp. The officer radios ahead to a highway patrol officer 30 km along the highway. 16 minutes later, the car reaches the location of the highway patrol officer and is clocked going 100 km/hr. The driver of the car is given a ticket for exceeding the 100 km/hr limit. wav patrol officer and is clocke Why can the officer conclude that the driver exceeded the speed limit?

Explanation / Answer

speed =distance/time

speed = 30*60/16

=117.5 km/hr

given speed = 100km/hr

therefore speed exceeds 117.5km/hr.-100km/hr =17.5 km/hr

2) if the time is 20 min later then the speed would be 90km/hr

steps : speed = 30*60/20

=90km/hr

the speed is less than the given speed.
