let the speed of car moving in opposite direction be v

distance =5km

velocities are added when objects are moving in opposite directions

so,

v=d/t

30+v=5/4/60

30+v=5×60/4

v=75-30

v=45


swati6958: i dont get the right answer but i got the hint how to solve it
swati6958: thnx for help
saariyahasan: yah! i think so it will be in this way only
