Question

The double number line shows that in 3 seconds an ostrich can run 63 meters . Based on the ratio shown in the double number line how far can the ostrich run in 5 seconds

Answer 1

3 seconds for 63 meters
then, 1 second for 21 meters
therefore, 5 seconds for 105 meters

Answer 2

Ostrich can run in 5 second = 105 meter .

Explanation:

Given : The double number line shows that in 3 seconds an ostrich can run 63 meters .

To find : Based on the ratio shown in the double number line how far can the ostrich run in 5 seconds.

Solution : We have given

ostrich can run in 3 second = 63 meter .

Let ostrich can run in 5 second = x meter .

By the Ratio : 63 : 3 :: x : 5

`(63)/(3) =(x)/(5)`

On cross multiplication

63 * 5 = 3 * x

315 = 3 x

On dividing both sides by 3

x = 105 meter .

Therefore, ostrich can run in 5 second = 105 meter .
