The boat went downstream for 0.8 hours and against the current for 0.3 hours. The boat’s own speed is 3.8 km / h

The boat went downstream for 0.8 hours and against the current for 0.3 hours. The boat’s own speed is 3.8 km / h and the current speed is 1.3 km / h. What way did the boat go during this time?

The path is found by the formula
S = Vt
In this problem, the path must be divided into two parts: along the river and against the river.
1) 0.8 * (3.8 + 1.3) = 4.08 (km) – path along the river
2) 0.3 * (3.8-1.3) = 0.75 (km) – the path against the river flow
3) 4.08 + 0.75 = 4.83 (km) – total
Answer: 4.83km
