You can put this solution on YOUR website! based on the question, i'm assuming you want to know how many miles per hour is 124 kilometers per hour.
the conversion factor would be 1 kilometer = 0.621371192 miles
multiply 124 by .621371192 and you get 77.05002781 miles per hour.
You can put this solution on YOUR website! given (124kph), how fast is the car moving to the nearest 10kph
================
To the nearest 10, it's 120 km/hr
