90 minutes
To convert hours to minutes, you multiply by 60 because there are 60 minutes in an hour. Therefore, 90 hours is equal to 90 x 60 = 5,400 minutes.
90 seconds = 60 seconds + 30 seconds = 1.5 minutes
At 80 km, you will go 120 km in 90 minutes.

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.
90 years = 47,335,389 minutes.
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.
3 hrs & 34 minutes is the same as 3.56666666666 hours. Divide this into 90 km and your answer is 25.233645 km/h (average)
Time taken = 34/90 = 17/45 of an hour or 22 and 2/3 minutes
