Question

If a rrain starts from meerut at 4 pm and reaches delhi at 5 pm and another train starts from delhi at 4 pm and reaches meerut t 5:30 pm then at what time tgey will meet

Answer 1

let the distance between meerut and delhi be x

train 1 takes 60 minutes

train 2 takes 90 minutes

when they meet time should be same

so consider train 1 travelled d then second must travel x-d

so d/(x/60)=(x-d)/(x/90)

solving we get d=3x/5

so time =d/(x/60)=36 minutes after 4 so they will meet at 4:36pm
