Speed= Distance/Time
Distance= 26 miles
Time= 1/2 hour
Speed=26/1/2=52
Speed= 52 miles/hour
Your new speed is 56.25 mph
It takes 3 hours to travel 79 miles.
Her average speed is 1.6 miles per hour. Average speed is total distance covered by total time taken to do it. She swims 4 miles upstream, and at 1 mph, it takes 4 hours. She comes back downstream at 4 mph and so she covers the 4 miles in 1 hour. Her total mileage is 8 miles. It takes 4 + 1 hours or 5 hours to cover it. The 8 miles divided by 5 hours is 1 3/5 miles per hour, or 1.6 mph for an average speed.
It takes approx 194 seconds, or 3.23 minutes.
'A' is slower. 'B' is faster. 'A' covers 220 miles, while 'B' covers 310 miles. 'B' gained 90 miles on 'A'. Since 'B' gains 18 miles on 'A' in each hour, it took (90/18) = 5 hours for 'B' to gain 90 miles on 'A', so both stated distances were covered in 5 hours. Speed of 'A' = 220/5 = 44 Speed of 'B' = A+18 = 310/5 = 62
40 mph
Average Speed = distance/time = 240/4 = 60 mph
The time it takes will depend on your average speed while traveling. In hours, it will be (490/speed in miles per hour).
1/18
W/4 mph
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.
The distance traveled by an object divided by the time it takes to travel that distance is called the average speed.[ Average ] Speed = Distance / TimeFor example :A car that travels 60 miles in a time of 2 hours has an average speed of 30 miles per hour.
You do 26 divided by 30 and get .866666666666 and so on so you round it to .87 miles/minute
260 + 90 miles takes 5 + 2 hours ie 330 m in 7 hr, so average speed is 330/7 ie Forty-seven and one-seventh mph
It takes (68 hours) divided by (the speed you travel, in miles per hour).
If the miles are nautical ones, then it takes (3)/(the boat's speed in knots) hours. If the miles are statute ones, then it takes (2.6053)/(the boat's speed in knots) hours.
The time it takes to travel 400 miles depends on the average speed. If the average speed is 50 miles per hour, you will travel 50 miles in the first hour, 50 more in the next, 50 more in the next and so on. The number of hours it will take is equal to the number of 50 mile stretches in 400 miles. That's 400 divided by 50, which is 8. It will take 8 hours to travel 400 miles at an average speed of 50 miles per hour. In general, if your average speed is s, then it will take 400 divided by s, or 400/s hours. Whatever the distance is, let's call it d, the time taken to travel is is d/s. It depends on the mode of transportation and the speed in which it is moving at.
