Question

A swimming pool is 1:2 m deep at one end, and 2 m deep at
the other end. The pool is 25 m long. Isaac jumps into the
pool 10 metres from the shallow end. How deep is the pool
at this point?

Answer 1

Answer:

13 , 15, 000 litres

step by step explanation

The cross section of the swimming pool is a trapezium with parallel sides 1.5m and 3m (depth of both ends) and 40m (length of pool) as the ⊥ r distance between ∥ sides.

The width of pool 1.5m can be the length of cross section.

Length of swimming pool=40m

Breadth of the pool=15m

Depth of the pool=1.5m and 3m

∴ Volume of the water=

1

[(1.5+3)×40]×15m

1

×4.5×40×15m

=1350m

Capacity of water in litres =1350×1000litres (1m

=1000litres)

=1350000litres

Answer 2
