If a swimmer swims 85.4 yards in 5 minutes, how many meters will he/ she swim in 70 seconds
DaniilM [7]

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.

There are 10 possible ways to select a president from the club, because their are 10 available members to choose from.

After a president is chosen, their are 9 possible ways to select a vice president, because one of the members will already have the position of president, so they can't be vice president (10-1=9)

Now we just multiply to possibilities of presidents by the possibilities of vice-presidents.

president*vicepresident=
10*9=90
