Question

Jason paddled his canoe 24 miles upstream for 4 hours.it took him 3 hours to paddle back. Find the speed of the canoe in still water and the speed of the current

Answer 1

24 miles in 4 hours upstream

3 hours back downstream

d=rt distance = rate of speed times time

let b= boat speed in still water, c= river's current speed

24 = (b+c)3, b+c=24/3 = 8

24 = (b-c)4, b-c = 24/4 = 6

2b =14,

b =7 mph for boat in still water

c = 8-7 = 1 mph for river current speed
