Answer 1

$\huge\underline\blue{\sf Answer:}$

$\large\red{\boxed{\sf n=0.44}}$

$\huge\underline\blue{\sf Solution:}$

$\large\underline\pink{\sf Given: }$

• Velocity of river ($\sf{v_R=3ms^{-1}}$

• Velocity of swimmer relative to water ($\sf{v_{SR}=5ms^{-1}}$

• Total distance travelled by swimmer(s) = 80m

• Time (t) = 22.5n

$\large\underline\pink{\sf To\:Find: }$

• Value of n = ?

━━━━━━━━━━━━━━━━━━━━━━━━

Relative Velocity :-

$\large{♡}$$\large{\boxed{\sf V_{SR}=v_S-v_R}}$

$\large\implies{\sf 5=v_S-3}$

$\large\implies{\sf v_S=5+3}$

$\large\implies{\sf v_S=8m/s }$

Now ,

$\large{♡}$$\large{\boxed{\sf Time(t)=\frac{Distance(s)}{Velocity (v_S)}}}$

$\large\implies{\sf 22.5n=\frac{80}{8}}$

$\large\implies{\sf n=\frac{10}{22.5}}$

$\large\implies{\sf n=0.44 }$

$\huge\red{♡}$$\large\red{\boxed{\sf n=0.44}}$

Hence ,

Value of n is 0.44

Answer 2

value of n is 0.44
