Question

steamer going downstream in a river cover the distance between two town in 20 hours coming back upstream cover the distance in 25 hours. the speed of water is 4 km/h find the distance between the two towns.

Answer:
Streamer going downstream cover the distance 20 hours.

Streamer going upstream covers the distance 25 hours.

speed of water 40km/h

= ( -4)

= ( +4)

Distance = Speed × Time

= (-4) ×20
= 20-80
= (+4)×25
= 25+100


,
20-80=25+100
-25+20 = 100+80
5 = 180
= 180/ 5
= 36


= 20+80
=20 × 36+ 80
= 720+80
= 800
