Correct Answer - Option 2 : 5 m

**Given: **

Speed of ball = 13 km/h

Hitting time = 3 s

Speed of person = 7 km/h

**Formula Used:**

Speed = Distance/Time

**Concept Used:**

If two objects are moving in the same direction with speeds S_{1} and S_{2},

Their relative speed is S_{1} – S_{2}

**Calculation: **

Relative speed = 13 – 7 = 6 km/h

⇒ 6 × 5/18 = 5/3 m/s

Using the above Formula,

Distance = 5/3 × 3 = 5 m

**∴ ****The person was standing 5 m away earlier.**
