12 minutes
60 minutes if you are travelling at 80 miles per hour
It's travelling at 44 miles per hour.
(18 miles) / (20 minutes) = (18 miles) / (1/3rd hour) = (3 x 18) mi/hr = 54 miles per hour.
If you are travelling at 60 miles per hour, then you will travel 144 miles in 2 hours and 24 minutes.
30 minutes is 1/2 hr. If you are travelling at 70mph, the in half an hour you will travel half of 70 which is 35 miles.
If you are travelling at the speed of 60 miles per hour, you will travel 133 miles in exactly 2.22 hours, or 2 hours and 13 minutes.
If you are travelling at 70 miles per hour then per minute you will be travelling at:70/60 = 1 1/6 miles per minute (we divided the 70 by 60 to convert the hours into minutes as there are 60 minutes in 1 hour).Of course, how far you will go depends on for how many minutes you travel at this constant speed!
The time of 20 mins is multiplied by 3 to get to the 'per hour" so car travels 18 miles times 3 = 54 miles per hour the answer is 54 mph
That depends on how fast you are travelling. If you are travelling at one mile an hour, then it would take you 6 miles. If you were travelling at 50 miles per hour, it would be 300 miles. So without specifying the speed you are travelling at, the question cannot be answered.
50 miles in 10 minutes is the same as 300 miles per hour, since 50 miles/10 minutes * 60 minutes/1 hour = 300 miles per hour
If travelling at a speed of 50 km per hour, this is the same as about 31 miles per hour.
Here is the explanation: 2 miles/16 minutes X 60 minutes/hour = 7.5 miles per hour
