Aman is walking across a 300 foot long field at the same time his daughter is walking towards him from the opposite end. the man is walking at 9 feet per second and the daughter is moving at 6 feet per second how many seconds will it take them to meet somewhere in the middle.

Let distance traveled by father be x feet

then distance traveled by daughter will be 300-x feet

speed = distance / time

and time = distance / speed

Since they both meet at the same time

cross multiplying gives

this gives x= 180 feet

So the distance traveled by father is 180 feet

Now time = distance/ speed

So time taken by father = = 20 seconds.

Hence it will take both of them 20 seconds to meet somewhere in the middle.
