How do you calculate distance?

Distance = Speed multiplied by Time. For example, travelling at 100 km/h for 2.5 hours covers 250 km.

How do you calculate travel time?

Time = Distance divided by Speed. For example, a 400 km trip at 100 km/h takes 4 hours.

Speed = Distance divided by Time. For example, if you travel 150 km in 2 hours, your average speed is 75 km/h.

Multiply km/h by 0.621371 to get mph. For example, 100 km/h is approximately 62.1 mph. To convert mph to km/h, multiply by 1.60934.

Results assume constant speed. Does not account for stops, traffic or acceleration.

Speed

Speed = Distance ÷ Time

e.g. 300 km ÷ 3 h = 100 km/h

Distance

Distance = Speed × Time

e.g. 100 km/h × 2.5 h = 250 km

Time

Time = Distance ÷ Speed

e.g. 400 km ÷ 100 km/h = 4 h

How do you calculate speed?

Speed = Distance ÷ Time. Travelling 150 km in 2 hours gives an average speed of 75 km/h.

How do you convert km/h to mph?

Multiply km/h by 0.621371. For example, 100 km/h ≈ 62.1 mph.
