A boat has to cross a river. It crosses the river by making an angle of `60^@` with the bank of the river due to the stream of the river and travels a distance of 600 m to reach the another side of the river. What is the width of the river?

Text Solution

Verified by Experts

let the width be p
according to figure
`sin 60^@ = p/600`
p = 600 xx sqrt3/2``
`p = 300 sqrt3 m`
