Answer:
The lorry is traveling at a speed of 13 m/s which is less than the speed limit of 13.89 m/s
Step-by-step explanation:
The limit here is 50km/h
The speed at which the lorry is traveling is 13.5m/s
So we want to show that the lorry is traveling at a speed which is below the speed limit.
What we need to do here is to convert the speed limit to the same unit at which the lorry is traveling
What we are saying here is that we need to convert km/h to m/s
Hence, we are converting 50 km/h to m/s
What we need to do here is to convert the km to m by multiplying by 1000 then covert the hour to seconds by multiplying by 3600(in this case the time is the denominator so we shall be dividing)
Thus 50 km/h = (50 * 1000)/3600 = 13.89 m/s
Since 13m/s is less than 13.89 m/s
Then the lorry is traveling below the stipulated speed limit
