sineoko [7]

Answer:

V(w)  = 26  miles/hour

Step-by-step explanation:

Let  

V(bu)  upstream boat speed         V(w) water speed

Speed upstream

V(bu)  =  24 /144       ⇒   V(b)  =   0,167  miles/min

V(bd)  =  24/40        V(bd)  =  0,6   miles/min

V(bd) =  V(b)  + V(w)

0,6 -0,167  = V(w)

V(w)  = 0,433 miles/min

or equivalent in miles /hour

V(w)  = 25.98 miles/hour

V(w)  = 26  miles/hour
