It takes 840 seconds to walk completely around a circular track, moving at a speed of 1.20 m/s. What is the radius of the track?
Added by Joanne A.
Step 1
We know that speed = distance/time. So, rearranging the formula, we get distance = speed * time = 1.20 m/s * 840 s = 1008 meters. This distance is the circumference of the circular track. The formula for the circumference of a circle is 2πr, where r is the radius Show more…
