A is walking with 4km/hr speed towards B and similarly B walks towards A with some speed
after 6 hrs A covers a distance of 24 km and it is said that both meet at this point
the remaining distance is 18km
so it is clear that B has walked 18 km in 6 hrs so the speed of B = 18/6 = 3km/hr
after 6 hrs A covers a distance of 24 km and it is said that both meet at this point
the remaining distance is 18km
so it is clear that B has walked 18 km in 6 hrs so the speed of B = 18/6 = 3km/hr

Where did 18 come from??
42-24
Why 42-24??
because A travels with a speed of 4km/hr for 6 hrs so he will be covering 4*6=24km in 6 hrs
Ok
Thank you
so the remaining distance B has to cover is 42-24=18
you're welcome
