1.	ing equaType IV. Problems based on speed8. A steamer covers the distance between two parts down the stream in 2 hours. It covers the same distance up theIf the speed of the stream be 3 km/hour. then find the speed of the steamer in still water.
Answer» Let speed of the steamer in still water=x=xkm/hr Speed downstream=(x+3)=(x+4)km/hrDistance between the ports=2(x+3)=2(x+3)km ---(1) Speed upstream=(x−3)=(x−4)km/hrDistance between the ports=3(x−3)=3(x−3)km ---(2) From (1) and (2)2(x+3)=3(x−3)2x+6=3x−9x=15

Answer»

Let speed of the steamer in still water=x=xkm/hr

Speed downstream=(x+3)=(x+4)km/hrDistance between the ports=2(x+3)=2(x+3)km ---(1)

Speed upstream=(x−3)=(x−4)km/hrDistance between the ports=3(x−3)=3(x−3)km ---(2)

From (1) and (2)2(x+3)=3(x−3)2x+6=3x−9x=15
