Abhishek and his friend go for a morning walk in a circular park whose circumference is 125m. They start from the same point and walk in opposite directions at 3.5 kmph and 2.75kmph respectively. After how much time will they meet for the first time?

Let the distance travelled by Abhishek and his friend be x and y respectively.
Then,x + y = 125 metres
Since distance = speed × time and also they will meet at the same time so let the time = t
Now,3.5t + 2.75t = 125
=>6.5t = 125
=>t = 125/6.5
=>t = 20
But strictly speaking you can't put a logical unit with the time,such as hours or minutes. You can put '20mh/km' which may seem awkward but that is just that!
You have made a typing mistake or else the question is wrong or complex since converting the units give an illogical answer.
