A runner Travels 1.5 laps around a circular track in a time of 50 sec. the diameter of track is 40 m and circumference is 126 metre find the average speed of the runner in meter/sec
Added by Andrea L.
Step 1
5 laps. Given that the circumference of the track is 126 meters, the total distance covered in 1.5 laps is: Total distance = 1.5 * Circumference Total distance = 1.5 * 126 Total distance = 189 meters Show more…

A runner travels $1.5$ laps around a circular track in a time of $50 \mathrm{~s}$. The diameter of the track is $40 \mathrm{~m}$ and its circumference is $126 \mathrm{~m}$. Find $(a)$ the average speed of the runner and $(b)$ the magnitude of the runner's average velocity. Be careful here; average speed depends on the total distance traveled, whereas average velocity depends on the displacement at the end of the particular journey.

A jogger jogs around a circular track with a diameter of 375 m in 15 minutes. what was the joggers average speed in m/s?
Nishant K.
A runner times his speed around a circular track with a circumference of $0.478 \mathrm{mi} .$ At the start he is running toward the east and the track starts bending toward the north. If he goes halfway around, he will be running toward the west. He finds that he has run a distance of $0.750 \mathrm{mi}$ in 4.00 min. What is his (a) average speed and (b) average velocity in $\mathrm{m} / \mathrm{s} ?$
