Answer 1

Answer:

Required Answer:

☪️ Concept behind the question:

Speed is the distance travelled in unit time.

It's a scalar quantity, so we just need the magnitude to express the speed of Salman.

Unit conversion is needed here in case of time, since speed is in m/s.

━━━━━━━━━━━━━━━━━━━━

According to the definition, Speed can be calculated by using the formula:

$\large{ \boxed{ \rm{Speed = \frac{Distance}{Time} }}}$

Then, Distance = Speed × Time.

Plugging the values:

➛ Distance = 0.5 m/s × 40 × 60s

➛ Distance = 1200 m (Ans)

Answer 2

Explanation:

Let the distance be x km.
