Question

A steamer goes downstream and covers the distance between two ports in 3 hours. It

covers the same distance in 5 hours when it goes upstream. If the stream flows at 3 km/hr,

then what is the speed of the steamer​

Answer 1

Answer:

5km/hr

Step-by-step explanation:

Given,

Speed while going upstream= 3km/h

Time taken while going upstream= 5 hours

Distance=?

WKT,

Distance= Speed × Time

So,

Distance= 3km/h × 5hours

D= 15km ---------(i)

And also given,

Time taken while going downstream = 3hours

Distance = 15km. [Using equation (i)]

Speed=?

WKT,

Speed = Distance

Time

S= 15km

3h

Speed = 5km/h

Hence, Speed of the steamer while going downstream is 5km/h
