Every day, the hour hand makes 2 complete revolutions and the minute hand makes 24 revolutions (one per hour). So we have 4 complete revolutions on the hour hand and 48 on the minute hand.
First, let us find out the distance per revolution these make. If you noticed on a clock, these would be considered radii, the minute hand makes:
C = 2πr
==> C = 2π(4)
==> C = 8π
==> C ≈ 25.133 cm/revolution
and the hour hand makes:
C = 2πr
==> C = 2π(6)
==> C = 12π
==> C ≈ 37.699 cm/revolution
So the sums are:
48(8π cm) + 4(12π cm)
= 384π cm + 48π cm
= 432π cm
≈ 1,357.168 cm
Therefore, the sum of the distances traveled is about 1,357 cm.
How you can use the speedometer and a clock to tall how far you've traveled in a car if the cars odometer is not working. Hint assume you are traveling at a constant velocity
By tracking the time it took to travel a certain distance at a constant speed using the clock, and noting the corresponding distance on the speedometer, you can calculate the total distance traveled. This can be done through the formula distance = speed × time. The speedometer provides the constant speed, and the clock helps measure the time taken during the journey.
Make sure the radio is on. Then hold the clock button and use the seek and tune buttons to change the hours and minutes respectively
A simple bicycle odometer tracks distance traveled, speed, and time elapsed. It typically displays this information on a digital screen and may have additional features like trip distance, average speed, and a clock. The odometer is usually mounted on the handlebars and uses sensors to measure wheel rotations to calculate distance.
You can use an equation: Distance = speed x time Assuming the car is moving at a constant speed for a certain time, the equation will provide the distance the car has traveled. Take a car that is doing 50 miles per hour for 90 minutes. Note that the speed refers to hours as the unit of time so the time used in the equation must also be in hours. Distance = 50 miles per hour X 1.5 hours Distance = 75 miles
Clock is to time as ruler is to distance.
The answer depends on how long the hand are!
Speed is equal to distance divided by time Algebraically s = d/t To do this mechanically, you need a clock/watch to measure the time. and some form of distance measure e.g. ruler, or mile posts. In a motor car you have the speedometer and odometer. They measure the speed at any given moment, and the distance travelled.
In an analog clock, the movement of the hour, minute, and second hands is based on a circular motion around the clock face. Each hand moves at a specific speed: the second hand completes a full rotation every 60 seconds, the minute hand every 60 minutes, and the hour hand every 12 hours. The distance traveled by each hand correlates with the time elapsed, as the constant speed of the hands allows for consistent measurement of time intervals. Thus, the combination of distance covered and the speed of movement enables accurate timekeeping.
