Question

7.

A coach travels from the station to the beach, a distance of 576km away in 6hrs.
The coach is only allowed to travel at a maximum speed of 90km/h. Did the coach
break the speed limit?

Answer 1

Yes.

Explanation:

distance = rate x time

Let r = rate

567 = r6 Divide both sides by 6

94.5 = r If he was driving at a constant rate the whole time then he was driving at 94.5 miles per hour which is faster than 90
