You drive 79 miles in 2 hours in a perfectly straight line.
What is your average velocity in kilometer per mile(round to the nearest 0.1 km/hour)?
(You may need to look up how many km = 1 mile.)
Total displacement travel = 79 miles
1 mile = 1.609 km
Total displacement in km = 79*1.609 = 127.1 km
Total time taken = 2 hours
Avg velocity = total displacement / total time taken
= 127.1/2 = 63.5 km/hour
