Answer 1

question is wrong please check

Answer 2

Answer:

The width of the river and speed of the river are 180m and 0.20m/s.

Explanation:

Given:

D = 75m

S = 195m

Here,

The distance that person gets carried away is denoted by D.

The width of the river is denoted by W.

The distance covered by the person is denoted by S.

The speed of the river is denoted by V.

Now,

By the equation,

$S^{2}=W^{2} +D^{2} \\195^{2}=W^{2} +75^{2} \\W = 180m$

Then,

By the equation,

$V=\frac{W}{T} \\V\frac{75}{360} \\V = 0.20m/s$

So, the width of the river and speed of the river are 180m and 0.20m/s.
