Question

Hannah is working in England for 3 months on a project for her company. One weekend Hannah decides to go to France with her car on the ferry, then explore the French countryside. In England, speed limit signs are posted in miles per hour (mph) and Hannah's rental car only shows the speed in miles per hour. In France, speed limit signs are posted in kilometers per hour (kph). Hannah looks up the conversion and learns that 1 kph = 0.62 mph.

On the road that Hannah is currently on, the posted speed limit is 130 kilometers per hour. What is the maximum whole-number speed, in miles per hour, that Hannah can drive without exceeding the speed limit??

A. 82 mph
B. 79 mph
C. 209 mph
D. 80 mph

Answer 1

Option D is correct
Explanation: I was doin sth like this last year

Answer 2

To convert 130 kph to mph, we can use the conversion factor 1 kph = 0.62 mph:

130 kph × 0.62 mph/kph ≈ 80.6 mph

So the maximum whole-number speed that Hannah can drive without exceeding the speed limit is 80 mph (option D).
