A speed limit in Europe is 80 km per hour. What is the speed in miles per hour? There are about 1.6 kilometers in 1 mile.

Question

A: 128 miles per hour
B: 50 miles per hour
C: 80 miles per hour
D: 75 miles per hour

Answer 1

To convert km/h to mph, we need to divide the speed in km/h by the conversion factor of 1.6.
Thus, 80 km/h divided by 1.6 equals 50 mph.
Therefore, the speed limit of 80 km/h in Europe is equal to 50 mph.
The correct answer is B: 50 miles per hour.
