(d) 28 hours
Let, 'd' be the total distance between A and B and
let 'M' be the meeting point.
Then, A covers V distance and B covers (d - x ) distance, before meeting

Also,

Let, us assume that the speed of car 1 and car 2 is 4y and 3y, respectively.
∴

x

4y

=

d−x

3y

⇒

=

d−x

⇒ 3x = 4d - 4x
⇒ 7x = 4d
⇒ x =

Now, it is given that car 2 covers

distance in 16 hours.
∴

= 3y
⇒

⇒
