Two towns are 20km apart. A biker leaves from the first town at 20km/h and another biker leaves the second town at the same time travelling 15km/h. Where and when will they meet?

Im confused on how to set up and solve this question some help would be appreciated

Use your formulae.

Since they travel at constant speed, you can use:



Since they meet at a fixed distance from town A and town B (I'll call them as such), the distance is not known. Let's call it 'x' being the distance from town A.
From A, the biker will travel x km
From B, the biker will travel (20-x) km.

This gives

20 = x/t
15 = (20-x)/t

Solve the simultaneous equation, the value for x gives you the distance from town A, and the time is the time passed between their departure and their meeting.

I hope it helped! :) Post your answer if you're not sure.
