1. Lauren’s SUV was detected exceeding the posted speed limit of 60 kilometers per hour?

Question

how many kilometres per hour would she have been travelling over the limit if she had covered the distance of 10 kilometres in 5 minutes?

Answer 1

Speed = distance / time

= 10 / {5/60}

=10 / (1/12)

=120Kmph

BART

Answer 2

v = s/t ; v=velocity; s=distance; t=time

so the velocity (in km/hour) is

v = 10/(5/60)

=120 km/hour

the question is: velocity over the limit (velocity limit is 60 km/hour)

so the answer is 120 - 60 = 60 km/hour
