Solution

The correct option is A 360 km

In 18 hours place will cover 18 $\times$ 120 = 2160 km
Now, $2160 = (600 \times 2) + 600 + 360$
So, the plane will be 360 km away from Kargil and it means it will be 240 km (600 - 360) away from Pukhwara.

A surveillance plane is moving between two fixed places Pukhwara and Kargil at 120 km/h. The distance between two places is 600 km. After 18 hours, what will be the distance between the Kargil and its position if it starts moving from Pukhwara?

The correct option is A 360 km In 18 hours place will cover 18 × 120 = 2160 km Now, 2160=(600×2)+600+360 So, the plane will be 360 km away from Kargil and it means it will be 240 km (600 - 360) away from Pukhwara.

The correct option is A 360 km

In 18 hours place will cover 18 $\times$ 120 = 2160 km
Now, $2160 = (600 \times 2) + 600 + 360$
So, the plane will be 360 km away from Kargil and it means it will be 240 km (600 - 360) away from Pukhwara.
