Along the perimeter of the pool, which has a rectangular shape with sides of 50 m and 25 m, it is pasted over with a special non-slip tape. How much time will the master spend if he glues 50 m of tape in 1 hour?

1) Let’s find out what perimeter the pool has, if it is known that it has a rectangular shape with sides of 50 m and 25 m.

(50 + 25) * 2 = 150 meters.

2) Let’s find out how long it will take to paste over 150 meters of the pool with a film, if it is known that 50 meters are pasted over in an hour.

150/50 = 3 hours.

Answer: the entire pool will be covered with foil in 3 hours.
