Decision (tick one box) Yes or No

Explanation

Yes, he is driving below the speed limit.

Step-by-step explanation:

Speed of the driver = 80 miles/hour

Speed limit in France = 130 km / hours

We have to compare both in order to know which is greater. Speed of driver is given in MILES/hour and speed limit is given iin KM/hour To compare, which should have both the speed of driver and speed limit in same units.

Lets convert the speed of driver in km/hour

1 mile = 1.61 km

SO

Speed of driver (km/hour) = speed of driver (miles/hour) · 1.61

Speed of driver (km/hour) = 80 (miles/hour) · 1.61

Speed of driver (km/hour) = 128.8 km/hour

As speed of driver (128.8 km/hour) is less than the speed limit, he is below the speed limit
