The average speed is 66.67 miles per hour.
You've done 600 miles in a total of 12 hours, therefore your average speed was 600/12 = 50 mph.
Assuming the same rate of speed, if it takes 2 people 6 hours to do a job, it will take 1 person 12 hours to do the same job. In each case, the number of work hours (2 x 6, 1 x 12) is the same.
Average speed = Total Distance/Total Time = 30 km/2.5 hours = 12 km/hour.
The time it takes to walk 12 kilometers depends on your walking speed. On average, a person walks at a speed of about 5 kilometers per hour. At this pace, it would take approximately 2.4 hours, or around 2 hours and 24 minutes, to complete 12 kilometers. However, individual speeds may vary, so the time could be shorter or longer depending on the walker.
The time it takes to walk 12 kilometers depends on your walking speed. On average, a person walks at a speed of about 5 kilometers per hour, which means it would take roughly 2.4 hours, or about 2 hours and 24 minutes, to walk 12 kilometers. If walking at a faster pace, it could take less time, while a slower pace would take longer.
The father's speed is 3 MPH, so the biker's speed is 6 mph. In 9 hours the biker would travel 54 miles
Given that the average person walks about 3 miles per hour, then it would take them 4 hours to walk 12 miles.
To calculate the average speed, divide the total distance traveled by the total time taken. In this case, if you travel 12 km in 4 hours, your average speed would be 12 km ÷ 4 hours = 3 km/h. Therefore, your average speed is 3 kilometers per hour.
A man hour is the product of a person multiplied by an hour. It is a unit of how long a task would take one person. A task that takes 12 man hours, for example, would take 12 hours for one person to complete, six hours for two people, four hours for three people, three hours for four people, etc. 1 man x 12 hours = 12 man hours 2 men x 6 hours = 12 man hours 3 men x 4 hours = 12 man hours 4 men x 3 hours = 12 man hours
To find Doug's average speed, divide the total distance he rowed by the total time taken. He rowed 3.12 miles in 12 hours, so the average speed is 3.12 miles ÷ 12 hours = 0.26 miles per hour. Therefore, Doug's average speed was 0.26 mph.

To find the speed, first convert 2 hours and 12 minutes into hours. This is 2 hours + 12/60 hours, which equals 2.2 hours. Then, dividing 26 miles by 2.2 hours results in approximately 11.82 miles per hour.
The average speed is 66.67 miles per hour.
To calculate the average speed for Tom's entire trip, we can use the formula for average speed, which is total distance divided by total time. Let's assume the total distance is (d). Tom walks half the distance ((d/2)) at 4 mph and runs the other half at 12 mph. The time taken to walk is ((d/2) / 4 = d/8) hours, and the time taken to run is ((d/2) / 12 = d/24) hours. The total time is (d/8 + d/24 = 3d/24 + d/24 = 4d/24 = d/6) hours, so the average speed is (d / (d/6) = 6) mph.
You've done 600 miles in a total of 12 hours, therefore your average speed was 600/12 = 50 mph.
