Question

In 9 hours 2 in of rain fell at this rate how many inches will fall in 12 hours​

Answer 1

2.67 in

Explanation:

∵ In 9 hours amount of rainfall = 2 in

∴ In 1 hours amount of rainfall = 2/9 in

∴ in 12 hours amount of rainfall = (2/9) × 12

=
`(24)/(9)` =
`(8)/(3)`

≈
`2(2)/(3)` in or 2.67 in.

In 12 hours 2.67 in. rain fell.

Answer 2

2 2/3 or

2.666667 inches rainfall or

8/3 inches of rainfall.

Explanation:

Set up a proportion. Since you are going to be looking for inches of rainfall, it should go in the numerator.

2 in rainfall/9 hours = x / 12 inches. Multiply both sides by 12

2*12 /9 = x

8/3 inches = x

2 2/3 inches should fall in 12 hours.
