Question

In the United States the speed limit signs are in miles per hour. Unfortunately, your speedometer only reads in km/hour. How fast are you allowed to go if the speed sign says 70 mph (rounded to the nearest hundredth)

Answer 1

The correct answer is 112.65 kph

Answer 2

The speed limit will be 112.65 kph.

Explanation:

In order to find how fast one can go when speed sign says 70mph and the speedometer reads in km per hour we convert mph to kmph.

The conversion unit is 1mph= 1.609344kph

So 70mph = 70x1.609344=112.6541kph

Or 70mph=112.65 kph

One can travel at 112.65 kph.
