A runner covers one lap of a circular track 40.0 m in diameter in 63.1 s
For that lap, what was her average speed?
I FIGURED IT OUT THX BRO
no prob dud
To calculate the average speed, we need to divide the total distance covered by the total time taken.
First, we need to calculate the distance covered in one lap of the circular track. The distance around the circumference of a circle is given by the formula:
Circumference = π × diameter
In this case, the diameter is 40.0 m. So, the circumference would be:
Circumference = π × 40.0 m
Now, we can calculate the distance covered in one lap:
Distance = Circumference
Next, we can divide the distance by the time taken to get the average speed:
Average speed = Distance / Time
Substituting the values:
Average speed = [π × 40.0 m] / 63.1 s
This calculation will give us the answer for the average speed of the runner.
