Can u find width of the River

Pardhu and Eswar are on the two opposite banks of a river. They both have a rowing boat.

They both start at the same time towards the opposite side.

• They pass each other at 180 meters from the bank where Pardhu departed. 
• When reaching the opposite bank, they both take a rest for the same amount of time before    they return.
• On the way back, they pass each other at 100 meters from the bank from where Pardhu        returned.

Pardhu and Eswar both row with a constant speed, but Eswar rows faster.
