Answer 1

Answer:

1.5 INCHES.

Step-by-step explanation:

✯Let us assume that the rate of falling of snow is x inches per hour.

Since the rate is uniform, the amount of snow dumped in 12 hours = 12x.

But according to the question, the amount of snow dumped in 12 hours = 18.

So, we have 12x = 18

Dividing both sides by 12, we get

$\frac{12x}{12} = \frac{18}{12}$

i.e. x= 3/2 inch/ hrs

Hence the amount of snow which fell in 1

hour = x = 3/2 = 1.5 inches

(✯Note:✯)

This question is a basic application of the unitary method.

In this method, if we are given that x items are equivalent to y objects

Then 1 item is equivalent to y/x objects.

In the given question we are given that in 12 hours 18 inches of snow fell

So, we have in 1 hour 18/12= 1.5 inches of snow fell.
