Answer 1

In 1970, a record 1.5 inches of rain fell in one minute at Brasse Terre, Guadalupe in the Caribbean. At this rate how much rain fell in 3 seconds or 0.05 of a minute? A 3 inches... B 0.075 inch... C 0.75 inch... D 30 inch. Pick one. Evan chose D as the correct answer. How did he get that answer?

Answer:

`0.075 inches`

Option B is correct.

Explanation:

Given.

The rain fall rate is 1.5 inches per minute.

How much rain fall in 3 second or 0.05 of minute?

First we find rain fall rate in one second.

`1.5 inch/min=(1.5)/(60) inch/second\\=0.025 inch/second`

So, 0.025 inches of rain fall in one second.

Therefore, the rain fall in 3 second is

`= 3* 0.025\\=0.075 inches`

The rain fall in 3 second is 0.075 inches.

If you chose option D is correct

If the rain fall is continue to 20 min at the rate of 1.5 inches per min, then the rain fall will be 30 inches.

The rain fall in 3 second is 0.075 inches.
