What is the average?

Question

An olympic swimmer swims 5.0 meters in 23.1 seconds. what is his average speed?

Answer 1

Average speed equals the total distance traveled over the time taken to transverse this distance.

Speed = Distance / time
Speed = d / t

The question states that the swimmer swam a distance of 5.0 meters.
d = 5.0 meters
The question also tells us that it took the swimmer 23.1 seconds to travel this distance.
t = 23.1 seconds

Speed = (5.0 meters) / (23.1 seconds)
Speed = .216 m/s
Speed = .22 meters per second

Answer 2

here is the formula for average speed,

Average Speed = Distance / Time

Since the person swam 5 metres in 23.1 seconds, just plug the numbers into the formula and you get 0.216 [m/s]

Answer 3

5 meters/ 23.1 Seconds = 0.216 m/s
=0.484 mi./hr
=0.710 ft/s

Answer 4

average speed is total distance over total time so the average speed would be:

v = d/t
v = 5.0m/23.1s
v = 0.216 (m/s)

Answer 5

That would be an average speed of:

6.825974025 megameters per year (if it's not a leap year),
or
6.844675324 megameters per year (if it is a leap year).
