An average speed of 40 miles per hour.
2 to 65
At double the speed, it's presumable that the five hours less is half of the time the trip took in the one direction - hence, the first trip took 10 hours. To travel 280 miles in ten hours, the average speed would be 28 MPH, and to halve that on the return trip, the average speed would be 56 MPH
You find out what the distance is and then divide it by the amount of time it took. You divide a known distance by the length of time it has taken to travel over it, this gives you speed. For instance if you travel 60 miles and it takes 1 hour, you divide 60 by 1, which leaves 60 so your speed is 60 miles per hour. If you travelled 60 miles and it took 2 hours then 60 divided by 2 is 30, so your speed was 30 miles per hour, and so on.
Speed is calculated as the distance an object travels, divided by the amount of time it took to go that amount of distance. For example - a car takes 2 hours to travel 80 miles. 80/2 is 40 - so it's speed is 40 mph.
An average speed of 40 miles per hour.
3 x 65 = 195
330 miles

154 miles / 5.5 hours = 28 miles / hour

Speed and velocity are different. Speed is how fast something's moving. Velocity is speed combined with the direction the thing is moving. Speed is calculated by dividing the distance traveled by the time it took to travel this distance. For example, if you drove 100 miles in two hours the speed would be 100 divided by 2 or 50 miles per hour.
The average speed is determined only by the total distance traveled and the total time. Thus, the average speed is: (1+10+60) / 6 = 11.83 mph
Speed is calculated as the distance an object travels, divided by the amount of time it took to go that amount of distance. For example - a car takes 2 hours to travel 80 miles. 80/2 is 40 - so it's speed is 40 mph.
Boats speed = 24 miles per hour.Current speed = 4 miles per hour.
