At 8:00 to 10:00 pace, you'd be running 24 to 30 minutes (respectively) for approximately a three-mile run to equate to nine miles of biking. 8,160 steps per hour. Multiply the miles per minute speed times 60 to convert the speed to miles per hour (mph). To further understand how this translates into miles per hour, divide this figure by 63,360. So, for instance, if a gear makes a full rotation every 4 seconds, we can calculate its angular speed as 90 degrees per second. The same 155-pound man engaging in 30 minutes of bike riding burns about 290 calories. Maybe 1 mile up hill and 7 or eight miles downhill. Considering the most basic case, the unit circle (a circle with radius 1), we know that 1 rotation equals 360 degrees, 360°. If the two wheels are front and rear wheel, both distances should be equal. That gives you the … Each revolution, the bike travels the distance equal to the circumference of the tire (unless you are skidding!) You can also estimate steps by knowing that 2,000 steps equals one mile. 1 See answer meganfox09 is waiting for your help. A flexible cable transmitted the number of rotations of the wheel to an analog odometer visible to the rider, which converted the wheel rotations into the number of miles traveled according to … 5 rotations? This is an extremely useful formula: it related these three quantities, so that knowing two we can always find the third. A bicycle tire is filled with air to a pressure of 610 kPa at a temperature of 19 oC. The SI unit symbol is RPM. To give you an example, on an e-bike my wife is using, ECO mode estimated battery life is 100km (62 miles), and SPEED mode (maximum level of electric assistance on this model) estimated battery life is only 36km (22 miles).
