Solution

The correct option is C $325 m$
The height of the hill = $400 m$
The distance Aswathi covered in 2 minutes = $- 5 m$
The distance she covered in half an hour = $- 5 \times \frac{30}{2} = - 5 \times 15 = - 75 m$
$∴$ Distance to be covered to reach the ground = $400 + (- 75) = 325 m$

The correct option is C 325 mThe height of the hill = 400 m The distance Aswathi covered in 2 minutes = −5 m The distance she covered in half an hour = −5×302=−5×15=−75 m ∴ Distance to be covered to reach the ground = 400 + (−75)=325 m

The correct option is C $325 m$
The height of the hill = $400 m$
The distance Aswathi covered in 2 minutes = $- 5 m$
The distance she covered in half an hour = $- 5 \times \frac{30}{2} = - 5 \times 15 = - 75 m$
