It takes a ship 3 hours to cover 72 km with the current and 4 hours against the current. Find the speed of the ship in still water and the speed of the current.
Well I had this problem for homework and the correct answers are the current is 3km/h and the speed of the ship is 21 km/h.
You are here too
ya that is correct
answer is 21 is speed of ship and 3 is speed of current
OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOoooHHHHHHHHHHHHH YEAAAAH
s + c = 72 / 3
s - c = 72 / 4
add the equations (to eliminate c)
solve for s
substitute back to find c
hello hello
yah yeet aksdkkdkjf math is so fun
