the tires on a bicycle have a diameter of 24 inches. if the tyres are turning at a rate of 50rev per minute, determine the bicycle's speed in miles per hour?
Answers
Answer:
Wheel Diameter = Wheel 2 x Radius; 50 cm / 2 = 25 cm.
For one rotation of the wheel, the distance travelled = circumference of the wheel.
Circumference = 2 x pi x radius = 2 x 3.1415926858 x 25 cm = 157.07 cm approx.
Distance travelled with 30 turns of the wheel = 30 x 157.07 = 4712.39cm approx.
Distance in meters = 4712.39cm / 100 = 47.12388 meters approx (1 cm = 1/100th of a meter).
Answer:
Distance in meters = 4712.39cm / 100 = 47.12388 meters approx (1 cm = 1/100th of a meter).
Explanation:
The unit miles consistent with hour (symbol: mph) is a size of velocity withinside the imperial and United States commonplace systems. It expresses the wide variety of statute miles traveled over the duration of 1 hour. One mph equals precisely 1.609344 kilometers consistent with hour (km/h). Simply divide 60 via way of means of your pace. When you are not the use of entire hours withinside the calculation, convert the wide variety to mins, then multiply the end result via way of means of 60 mins consistent with hour to get miles consistent with hour or kilometers consistent with hour. Below are a few pattern velocity calculations: Running 6 miles in 1 hour: 6 / 1 = 6 miles consistent with hour (mph)
Wheel Diameter = Wheel 2 x Radius; 50 cm / 2 = 25 cm.
For one rotation of the wheel, the gap travelled = circumference of the wheel.
Circumference = 2 x pi x radius = 2 x 3.1415926858 x 25 cm = 157.07 cm approx.
Distance travelled with 30 turns of the wheel = 30 x 157.07 = 4712.39cm approx.
Distance in meters = 4712.39cm / 100 = 47.12388 meters approx (1 cm = 1/one centesimal of a meter).
