Question

Two bikers are riding a circular path.

The first rider completes a round in 12
minutes. The second rider completes
a round in 18 minutes. If they both
started at the same place and time
and go in the same direction, after
how many minutes will they meet
again at the starting point?

Please show working

Answer 1

Find the LCM of 12 & 18 .

12 = 2×2×3

18 = 3×3 ×2

So , LCM of ( 12 , 18 ) = 2×3×2 = 36

Your Ans is 36

Therefore he meet after 36 minutes at starting point..!!

Hopefully u will satisfy with my answer of ur question..!!

Have a nice day ahead dear..!!

Two bikers are riding a circular path.

The first rider completes a round in 12

minutes. The second rider completes

a round in 18 minutes. If they both

started at the same place and time

and go in the same direction, after

how many minutes will they meet

again at the starting point?

`\huge \mathfrak \orange{Solution}`

`\huge \mathsf \blue{Given}`

• First rider takes 12 minutes to complete a round.
• Second rider takes 18 minutes to complete a round.

`\huge \mathsf \blue{To\: Find}`

After how many minutes will they meet

again at the starting point?

Take the LCM of 12 and 18

12 = 2 × 2 × 3

18 = 2 × 3 × 3

Thus, the LCM of 12 and 18 is 36.

So they will meet after 36 minutes again at the starting point.
