Rate for 40 meters in 10 seconds?
Viefleur [7K]
The rate for 40 meters in 10 seconds is

40m/10sec (40 meters per 10 seconds)

You can turn it into a different unit of measurement by multiplication or division.

For example, if you want the rate in 1 second, you divide both units by 10 (because there are 10 seconds, and 10 ÷ 10 = 1).

40m/10sec then becomes

4m/1sec (4 meters per 1 second)

40 ÷ 10 = 4, and 10 ÷ 10 = 1

Or if you'd like it in minutes, you multiply both units by 6 (because there are 60 seconds in 1 minute, and 6 x 10 = 60).

40m/10sec becomes

240m/60sec = 240m/1min

40 x 6 = 240, 10 x 6 = 60 = 1 minute
