Question

a steamer goes 48 km downstream in 24 hours if takes 4 hours more to cover the same distance against the stream what is the speed of the boat in still water​

Answer 1

let the speed of the boat be x.

then,x=24-4=48km

x=20=48km

x=km=48/20

x=km=12/5

x=km=2.4

hence the speed of the boat is 2.4 km per hr.

thank u plz mark me as brainliest.............
