A cyclist rides at 5 m per second .the wheels of his bicycle have a circumference of 125 cm .how many complete turns does each wheel make in 5 seconds.

To calculate the number of complete turns each wheel makes, we need to find the distance traveled by the cyclist in 5 seconds and then divide it by the circumference of the wheels.

1. Convert the circumference of the wheels from centimeters to meters.
The circumference is 125 cm.
1 meter = 100 centimeters, so 125 centimeters equals 1.25 meters.

2. Calculate the distance traveled by the cyclist in 5 seconds.
The speed of the cyclist is 5 m/s.
Distance = Speed x Time
Distance = 5 m/s x 5 s = 25 meters.

3. Calculate the number of complete turns each wheel makes.
The distance traveled per complete turn is equal to the circumference of the wheel.
Number of turns = Distance / Circumference
Number of turns = 25 meters / 1.25 meters = 20 turns per wheel.

Therefore, each wheel makes 20 complete turns in 5 seconds.

To find the number of complete turns the wheel makes in 5 seconds, we need to determine how many times the wheel rotates in that time period. We can use the formula:

Number of turns = Distance travelled / Circumference of the wheel

Given that the cyclist rides at 5 m per second and the wheel has a circumference of 125 cm (or 1.25 m), we can calculate the number of turns:

Distance travelled = Speed × Time
Distance travelled = 5 m/s × 5 s = 25 m

Number of turns = 25 m / 1.25 m = 20

Therefore, each wheel makes 20 complete turns in 5 seconds.

5m/s * 100cm/m* 1rev/125cm * 5s = 5*5*100/125 rev
