Answer 2

Given:

10 km per hour and 30 km per hour.

To find:

The ratio of 10 km per hour to 30 km per hour.

Solution:

The correct option is (c) 1 : 3.

To answer this question, first of all, we should know that the ratio of two numbers a and b is equal to

$\frac{a}{b}$

After solving,

a/b can be written as

a:b

Also, the two numbers must have the same units.

Now,

As given, we have,

10 km per hour and 30 km per hour

So,

The ratio of 10 km per hour to 30 km per hour is

$= \frac{10}{30}$

$= \frac{1}{3}$

= 1:3

Hence, the ratio of 10 km per hour to 30 km per hour is (c) 1 : 3.
