Question

answer question no. 16 plzz​

Answer 1

Here, we need to find the LCM of the 3 numbers.

If we take the numbers as 1cm 2cm and 3cm, the LCM would be 6cm. This means that all the 3 people will meet at 6cm.

LCM of 80, 85 and 90 = 2×2×2×2×3×3×5×17

= 12240 cm

Which means that they will have to cover a minimum distance of 122m and 40cm to meet.

Hope this helps :)
