Answer 2

$\huge{\underline{\underline{\red{Answer}}}}$

━━━━━━━━━━━

$\mathbb{\boxed{\pink{GIVEN}}}$

• Speed = 20km/hr
• Time taken = 15min

━━━━━━━━━━

$\mathbb{\boxed{\pink{NEED\:TO\:FIND}}}$

• Distance travelled=?

━━━━━━━━━━━━━━

$20km/hr = \frac{20 \times 1000m}{1 \times 3600sec} \\ \implies \: 20km/hr = \frac{20000m}{3600sec} \\ \\ \implies \: 20km/hr = \frac{50m}{9sec}$

━━━━━━━━━━━━

Now total time taken is

$15min \\ = 15 \times 60sec \\ =900sec$

━━━━━━━━━━━

in 9sec he travels 50m

in 1 sec he'll travel $\frac{50}{9} m$

in 300 sec he travels $\frac{50}{9} \times 900m \\ = 50 \times 100m \\ = 50000m\\ =5km$
