A boat travels 42 km downstream in 3 hours and returns the same distance upstream in 6 hours. After a while, the speed of the stream increases by 2 km/hr. If the boat again travels 42 km downstream at the new effective speed, how long will it take?
- 2.265 hours
- 2.625 hours
- 2.526 hours
- 2.652 hours
