Question

A boat can travel 6.5 km upstream in 26 minutes. It can travel 7.5 km in 15 minutes What is the speed of the boat in still water 2 (in kmph)

Answer 1

Step-by-step explanation:

A boat can travel 6.5 km upstream in 26 minutes. It can travel 7.5 km in 15 minutes What is the speed of the boat in still water? (in kmph)

• Let the speed of the boat in still water be x and speed of the stream be y  
• Now speed of boat in upstream will be 6.5 (x – y) and speed of boat in downstream will be 7.5 (x + y)
• Now we have the equations  
• 6.5 (x – y) = 26
• 7.5 (x + y) = 15
• (x – y) = 26/6.5
• (x + y) = 15/7.5
• So (x – y) = 4
•     (x + y) = 2
•    2x = 6      
• Or  x = 3        

Therefore speed of boat in still water is 3 km/hr

(Upstream speed should be lower than downstream speed so question should be corrected)
