Question

If a swimmer swims 85.4 yards in 5 minutes, how many meters will he/ she swim in 70 seconds

Answer 1

Distance swam in 5 minutes = 85.4 yards

Since, 1 min = 60 seconds and 1 yard = 0.91 meter

5 minutes =
`5 * 60 = 300` seconds

85.4 yards =
`85.4 * 0.91 = 77.7` meters

So, Distance swam in 300 seconds = 77.7 meters

Now, we will use unitary method to determine the distance swam in 70 seconds.

Distance swam in 1 second =
`77.7 / 300` = 0.26 meter

So, Distance swam in 70 seconds =
`70 * 0.26`

= 18.2 meters

Therefore, the swimmer took 70 seconds to cover the distance of 18.2 meters.
