1. A swimmer can swim 1000 m in 360 seconds. What is her average speed in m/s?

Question

i really want to know the answers to make this much much easier.

 

Answer 1

The "/" symbol let's you know to use division. So they are asking for her average speed in meters per second, or meters divided by seconds.

 

The number of meters she travelled is 1000 meters and the time she travelled that distance is 360 seconds.

 

m/s = 1000m / 360s (1000 meters divided by 360 seconds)

      = 2.78 m/s

 

Answer 2

Average speed = total distance traveled / time taken

                      = 1000 / 360

                      =  25/9  (m/s)
