1. 132 km
2. 128 km
3. 120 km
4. 102 km

Answer 1

Correct Answer - Option 2 : 128 km

Given:

The speed of 20 km/hr instead of 16km/hr

Distance = 32 km more

Formula used:

Distance = Speed × Time

Calculation:

Let the actual distance be x km

According to the question:

(x/16) = (x + 32)/20

⇒ 20x = 16x + 512

⇒ 20x – 16x = 512

⇒ 4x = 512

⇒ x = 128

∴ The actual distance is 128 km.
