To calculate the time taken to cover a distance, you can use the formula:
Time = Distance / Speed
In this case, the distance is 250 km, and the speed is 50 km/h.
Time = 250 km / 50 km/h
Simplifying the equation:
Time = 5 hours
Therefore, it will take 5 hours to cover a distance of 250 km at a speed of 50 km/h.
