Question

You are driving west on highway 510 in a European car. The speed limit for this portion of the highway is 50 miles per hour. Your speedometer reads 120 km/hr. Are you speeding or not? How fast are you traveling in mph? (1 km =0.621 miles)

Answer 1

Divide 50 miles an hour or mph by 0.621, should give you 80.51 kilometers an hour or km/hr, this being the speed limit on that street in km/hr. If you're going 120 km/hr on an 80.51 kilometers an hour road you are speeding, as you're above the speed limit.
