The question cannot be answered without information about the radius.
To convert 139 yards in 25.75 seconds to miles per hour, first calculate the speed in yards per second. Then convert yards to miles (1 mile = 1760 yards). Finally, convert seconds to hours (1 hour = 3600 seconds). Calculate the speed in miles per hour using the obtained values.
To convert miles per hour to seconds, you need to know the distance covered in a specific time period. Miles per hour is a unit of speed, while seconds are a unit of time. Without additional information, it is not possible to directly convert 126 miles per hour into seconds.
speed = distance / time Speed(mph) = (19/1760) / ( 2.5/3600) Division of fractions. speed = 19/1760 X 3600/22.5 Cancel dowm by '10' speed(mph) = 19/176 X 360/2.5 Cancel down by '2' speed = 19/88 x 180/2.5 Cancel down again by '2' speed = 19/44 x 90/2.5 And again speed = 19/22 x 45/2.5 Convert the 2.5 to a fraction 2.5 = 2 1/2 = 5/2 speed = 19/22 X 45 / ( 5/2) becomes speed = 19/22 X 90/5 Cancel down by '5' Speed = 19/22 X 18/1 Cancel down by '2' Speed (mph) = 19/11 X 9/1 Multiply out Speed = 171/11 = 15 6/11 mph or 15.545454.... mph. NB Yes I have made 'heavy weather' of it , but it is done to show methods of calculation, without using a calculator. NNB To compare the faster 100 metre runners in under 10 secs, are only speeding at about 23 mph.
To determine how many miles per hour you can mow a lawn of 100 feet in 30 seconds, first convert feet to miles (1 mile = 5280 feet), then convert seconds to hours (1 hour = 3600 seconds). After these conversions, you can calculate the speed in miles per hour.
First, convert the hours to seconds:10 miles/hour x 1 hour/3600 seconds = .002777 miles/secondNext, convert the miles to feet:.002777 miles/second x 5280 feet/mile = 14.67 feet/second
To convert miles per hour to feet per second multiply by 5280 (feet in a mile) and then divide by 3600 (seconds in an hour).
To convert 4.4 miles per hour per second to meters per second squared, first convert 4.4 miles to meters (1 mile = 1609.34 meters) and 1 hour to seconds (1 hour = 3600 seconds). Then divide the speed in meters per second by the time in seconds squared to get the acceleration in meters per second squared.
Well, let's see here. If you run 40 yards in 4.5 seconds, that's like running about 120 feet in a little over 4 seconds. If we convert that to miles per hour, it would be around 16.36 miles per hour. Just imagine yourself running through a beautiful forest, feeling the wind in your hair at that speed!
21 hours 25 minutes 42 seconds
miles per hour * 22/45 = yards per second
k seconds per mile = 3600/k miles per hour.
To convert 1200 meters in 2 minutes and 32 seconds to miles per hour, you would first convert the distance to miles (0.75 miles), then convert the time to hours (0.042 hours). Finally, you would divide the distance by the time to get the speed in miles per hour, which would be approximately 17.85 miles per hour.
