Problem

Mira rowed upstream in a stream flowing at the rate of 1.5 km/hr to a certain point and then rowed back stopping 2 kms short of the place where she originally started. If the rowing time was 2 hours 20 minutes and her uniform speed in still water was 4.5 km/hr, how far upstream did she go?

1. 4.25 kms
2. 5.33 kms
3. 6.50 kms
4. 7.00 kms
5. 8.75 kms
