Approximately 1 hour 40 minutes
Speed is defined as distance covered per unit of time, so distance divided by speed equals time. For example, if you are travelling for 200 miles at a speed of 60 miles per hour, 200 miles/60 mph = three and a third hours.
Speed = Distance / Time = 28 miles / 30 minutes = 56 miles per hour - on average.
distance = speed x time first get speed in miles per minute: 80 mph/60 = 4/3 miles per minute distance = 4/3 x 45 minutes = 60 miles
It depends on the speed at which you are travelling.
50mph
That depends entirely at what speed you're travelling !

This is entirely dependent upon the speed you are travelling at. Speed = distance / time Rearranging, we find that time = distance / speed If you are travelling at 70 miles per hour for 15.1 miles then we can calculate the estimated time to be 15.1/75 which is equal to 0.201. This is how many hours it will take. We simply multiply by 60 to achieve the time in minutes which is 12.08
Either acceleration, average speed, direction, or instantaneous speed.
It depends what speed the car is travelling at !.. At 60mph - it will take 4 minutes... At 120mph it will take 2 minutes.
Then your speed is precisely (70 miles per 200 minutes).If you do the division of (70/200), you find the more familiar unit rate:(70 miles / 200 minutes) = 0.35 mile/minute = 21 miles/hour .
It is always 3600 seconds per hour: the speed at which you are travelling is totally irrelevant.
Approximately 1 hour 40 minutes
It depends on what speed you are travelling.
Speed = (distance) divided by (time for the distance) Your speed would be exactly 27 miles per 20 minutes. In more familiar units . . . 20 minutes = 1/3 hour 27 miles / (1/3 hour) = 81 miles per hour.
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.
