Problema Solution
On the Mississippi river, a steamboat can travel 39 miles downstream in the same time it can travel 24 miles up stream. If the speed of the current of the Mississippi rivver is 5 mph, then how fast is the steamboat? Show all five problem solving steps
Answer provided by our tutors
speed down = 39/t
speed up = 24/t
let speed of boat = s
also 39/t = 5+s (1)
24/t = s-5 (2)
divide 1 and 2 solving eqns we get t= 1.5 hour
so speed "s" of boat = 21 mph
