- A man can push upstream at 6km/hr and downstream at 10 km/hr.
Question 1:
A man can push upstream at 6km/hr and downstream at 10 km/hr. Discover man's rate in still water and the rate of the momentum. A. 4,5 km/hr
B. 5,6 km/hr
C. 6,8 km/hr
Feedback Speed upstream =6 km/hr
Speed downstream = 10 km/hr
Rate in still water = 1/2 (10-6) km/hr. = 6km/hr
Rate of the current = 1/2 (10+6) km/hr =8 km/hr
Speed downstream = 10 km/hr
Rate in still water = 1/2 (10-6) km/hr. = 6km/hr
Rate of the current = 1/2 (10+6) km/hr =8 km/hr
D. 7,9 km/hr
