Question

Traveling with the current a certain boat went 16km/h. Against the same current it only went 6km/h. Find the current and the speed of the boat if there were no current.

Answer 1

Answer:

Step-by-step explanation:

b and c are the speeds of the boat in stool water, and current, respectively.

Going with the current, the boat travels b+c=16 km/h.

Going against the current, the boat travels b-c=6 km/h

add the equations together

b+c = 16

b-c = 6

2b = 22

b = 11

c = 16-b = 5
