To determine the time it will take to cover a distance, you can use the formula:
Time = Distance / Speed
In this case, the distance is 100 km, and the speed is 80 km/h. Plugging these values into the formula:
Time = 100 km / 80 km/h
Simplifying the expression:
Time = 1.25 hours
Since the speed is given in kilometers per hour and the distance is in kilometers, the time will be in hours. Therefore, it will take 1.25 hours (or 1 hour and 15 minutes) to cover a distance of 100 km at a speed of 80 km/h.
