12 minutes.
(10/100) - (10/120) = 1/10 - 1/12 = 6/60 - 5/60 = 1/60 hour i.e. one minute.
You can go 7.5 miles driving at 15 miles per hour for 30 minutes. This is because 30 minutes is 1/2 of an hour, and 1/2 of 15 miles (the distance you travel in an hour) is 7.5 miles.
It depends on the speed you are driving. At 50 miles per hour, you would travel 8 miles in 6.25 minutes.
This depends on how fast you are driving. If you are going sixty miles per hour on the highway, you would go 60 miles in one hour.
It will take: 30/40 = 3/4 of an hour
60 miles
That depends on the speed at which you are driving. For example, if you are driving 52.6 miles/hour, it would take an hour to drive that far. If you are driving 23.8 miles/hour, it would take two hours to drive that far.
If you were driving 65 miles per hour how long will it take you to drive 310 miles?
It requires 1 hour of driving time if the driving time is maintained at a steady or at least average of 77 miles per hour. If the driving time averages 60 miles per hour, the driving time will increase to one hour and 17 minutes.
Errr, that would be 70!
(10/100) - (10/120) = 1/10 - 1/12 = 6/60 - 5/60 = 1/60 hour i.e. one minute.
80mph = 80 miles/hour If you drive for one hour at 80 miles/hour, you will travel 80 miles.
5.24 hours.
One hour.
You take the miles per hour you ate driving and divide it by 60
1 hour and 32 minutes.
25 kph equates to 15.5 miles per hour.
