At 120 km/h, in 45 minutes (which is 0.75 hours), a vehicle would travel 120 km/h * 0.75 h = 90 km.
about 60-90 km
5,400 minutes.
0.9 km = 900 mTo convert from km to m, multiply by 1000.
The average speed is calculated by dividing the total distance by the total time. In this case, the average speed would be 16 km/hour since 24 km divided by 1.5 hours (90 minutes converted to hours) equals 16 km/hour.
90 years = 47,335,389 minutes.
