Question

a swimming pool is filled 3/10 part in half an hour. how much will it be filled in 1 1/2 hour ​

Answer 1

Step-by-step explanation:-

Part filled in half hour = 3/10

So, part filled in 90 (1 1/2 hours) minutes:-

= 3/10 x 3

= 9/30

= 30 %

now we know that in 30 minutes, 30 % of the poll is filled.

So, now in 90 minutes (1 1/2 hours),

We multiply by 3

= 30 % x 3

= 90 %

So, your answer is 90 %

It equals 9/10th of the pool.

Answer 2

The answer is 2/5 part of the swimming pool.

GIVEN

A swimming pool is filled 3/10 part in half an hour.

SOLUTION

How much will it fill in

$1 \frac{1}{2} hr$

a

SOLUTION

We can simply solve the above problem as follows;

It is given in 1/2 hour, 3/10 part of swimming poll is filled.

Applying simple unitary method;

Part of swimming pool filled in 1 hour =

$= \frac{3}{ \frac{10}{ \frac{1}{2} } }$

$= \frac{3}{10} \times \frac{2}{1} = \frac{3}{ 5}$

So, in 3/2 hour, Part of the swimming pool filled =

$\frac{3}{ \frac{5}{ \frac{3}{2} } } = \frac{3}{5} \times \frac{2}{3}$

= 2/5 part

Hence, The answer is 2/5 part of the swimming pool.
