Best Answer

Please use the formula:

distance = speed x time

Replace the variables you know, and then calculate the remaining variable with this formula.

To find average speed, divide the distance travelled by the time it takes to travel that distance. In this instance, 60 / 3 = 20. Therefore, you would need to travel at an average speed of 20 miles per hour.

160.9344 kilometers per hour

To calculate the time it would take to travel 200 miles, divide the distance by the average speed. Assuming an average speed of 40 MPH (miles per hour). 200 ÷ 40 = 5 hours At 33 MPH it would be about 6 hours.

It depends on your average speed. If the roads permit an average speed of 60mph, it would take you 5 hours. To work it out (using T=D/S): Time (hours) = 300 miles divided by average speed (mph)

To travel 145 miles in 3.5 hours requires an average speed of 145/3.5 mph. The distance traveled at this speed for 5 hours would be approximately 207 miles (5 x 145/3.5 miles).

Your average speed would be 77.65 kilometers per hour to travel 330 kilometers in 4.25 hours. This is calculated by dividing the total distance by the total time taken to travel that distance.

There are no "hours" in any distance. If the question is really "How long would it take to travel 721 miles?" then the answer depends on the average speed, which depends on the mode of travel.

It depends on speed, but assuming an average of 12mph, about 130 hours

That would depend on the average speed. If the average is 50 mph, they drove 650 miles.

Divide 180 by the average speed (60) and you will have your answer.

The average speed would be 280 miles divided by 6 hours, which equals 46.67 miles per hour.
