Here’s and example of a SMART MATH problem for TIME SPEED DISTANCE.
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?
- 4.25 kms
- 5.33 kms
- 6.50 kms
- 7.00 kms
- 8.75 kms
