The diameter of each wheel of a bicycle is 26 inches. If you are traveling at a speed of 35 miles per hour on this bicycle, through how many revolutions per minute are the wheels turning?
yeah you can push them down so they look and fit right
Turn wipers off first before the ignition switch!! ?:)
turn your ignition key so that it powers the instrument panel and radio but not so much that it starts the car. This will powerthe wipers also and when they rest at the bottom turn off the wipers and turn off the ignition. Most cars' wipers behave like yours
Let’s convert miles per hour to feet per minute. 1 mile 5280 ft, 1 hour 60 minutes 1 mph 5280/60 88 ft/min 35 mph 35 * 88 3080 ft/min As the wheel rotates one time, the bicycle moves a distance which is equal to the circumference of the circle. C 2 * π * r, r 13 in C 2 * π * 13 26 * π in Let’s convert inches to feet by dividing by 12. C 26 * π ÷ 12 13/6 * π ≈ 6.807 ft This is the distance the bicycles moles as the wheel rotates one time. To determine the number of revolutions per minute, divide 3080 ft by this distance. 3080 ÷ (13/6 * π) The answer is approximately 452.5 rpm Sorry about my mistake!
Circumference is pi* diameter. A wheel with a diameter of 26 inches will have a circumference of 26*pi 81.68141 inches. So the wheel will travel 81.68141 inches for each revolution. 35 miles/hour x (5280 feet/1 miles) x (12 inches/1 foot) x (1 hour/60 minutes) x (1 rev/81.68141 inches) 452.4897 RPM. To the two significant figures provided in the original data, the answer would be 450 RPM.
