The boat’s own speed is 8 km / h. the boat went 0.6 hours downstream and 0.8 hours against the current. what way did the boat go during all this time if the current speed is 2.5 km / hour?
Boat speed downstream:
Vpo = 8 + 2.5 = 10.5 km / h.
Boat speed upstream:
Vpposite = 8 – 2.5 = 5.5 km / h.
The boat went downstream a path equal to
Spo = Vpo * Tpo = 10.5 * 0.6 = 6.3 km.
Against the current, the boat traveled a path equal to
S versus = V versus * T versus = 5.5 * 0.8 = 4.4 km.
The total distance covered by the boat during the considered time:
S = Spo + S versus = 6.3 + 4.4 = 10.7 km.
Answer: 10.7 km.
