To calculate the time it will take to cover a distance of 100 km at a speed of 80 km/h, you can use the formula:
Time = Distance / Speed
Plugging in the values:
Time = 100 km / 80 km/h
Time = 1.25 hours
Since time is typically measured in hours, you can convert the decimal value to minutes by multiplying by 60:
1.25 hours * 60 minutes/hour = 75 minutes
Therefore, it will take 1 hour and 15 minutes (or 75 minutes) to cover a distance of 100 km at a speed of 80 km/h.
