Question

Once a sports goods retailer organized a campaign “Run to remember” to spread awareness about benefits of walking. In that Soham and Bani participated.There was a circular path around a sports field. Soham took 12 minutes to drive one round of the field, while Baani took 18 minutes for the same. Suppose they started at the same point and at the same time and went in the same direction.(a)After how many minutes have they met again at the starting point(b)What’s your view about walking?

Answer 1

a)Time taken by Soham to drive one round of the field= 12 min
Time taken by Bani to drive one round of the field= 18 min

LCM of 18 and 12 gives the exact number of minutes after which they will meet at the starting point again.

Prime factorization of 18 and 12:
18 = 2× 3×3 = 2¹× 3²
12= 2×2×3 = 2² × 3¹

LCM of 18 and 12= 2² × 3² = 2×2 × 3×3 = 36.
Hence, Soham and Bani will meet again at the starting point after 36 minutes.

b) walking is good for health. It increases the stamina in the body and makes us fit and healthy. It is good for heart.

HOPE THIS WILL HELP YOU....

Answer 2

Given:

Soham and Baani took 12 minutes and 18 minutes respectively to drive one round.

To find:

When they will see each other again at their starting point.

Answer:

Given that,

To drive for one round of the filed soham and baani took 12 minutes and 18 minutes respectively.

Calculate LCM (12, 18) is

$12 = 2 \times 2 \times 3$

$18 = 2 \times 3 \times 3$

$LCM (12, 18) ={2} \times {2} \times {3} \times {3}=36$

After 36 minutes, they will see each other at the starting point.

Walking is needed to improve one's health and heart in the morning times and because of walking stamina of the body will increase.
