Answer 2

Answer:

The lightning struck at a distance of 1020 m.

Explanation:

Given data:

• Time (t) = 3 sec

• Velocity of sound in air = 340 m/s

To find:

Distance

Solution:

We know that,

Velocity = Distance/Time

→ Distance = Velocity × Time

Now by substituting the know values, we get

Distance = 340 × 3

= 1020 m

Hence, the lightning struck at a distance of 1020 m.
