Question

what will be the greatest possible speed ( in km/hr) at which a bird should fly to cover a distance of 45 km and 336 km in exact number of hours

Answer 1

Given:

The bird should fly to cover a distance of 45Km and 336Km in exact number of hours.

To Find:

What should be the greatest possible speed at which a bird should fly.

Solution:

Inorder to find the greatest possible speed at which bird should fly,

we can find the HCF of 45 and 336.

• Factors of 45 = 5 x 3²
• Factors of 336 = 3 x 112 = 3 x 28 x 4 = 3 x 4² x 7

Here the highest common factor is 3.

The greatest possible speed at which the bird should fly is 3Km/hr.

Answer 2

Step-by-step explanation:

factories of 45 5*3³

factories of 336 3*112=3*29*4=3*4²*7
