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 = $5 \times 60 = 300$ seconds

85.4 yards = $85.4 \times 0.91 = 77.7$ 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 = $77.7 \div 300$ = 0.26 meter

So, Distance swam in 70 seconds = $70 \times 0.26$

= 18.2 meters

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