Best answer

(c) 240 km

Distance covered by goods train before express train leaves = 40 × 2 = 80 km 

Relative speed = (60 – 40) km/hr = 20 km/hr 

∴ Time taken to cross each other = \(\frac{80}{20}\) hrs = 4 hrs 

∴ Distance from Delhi where the express train is expected to overtake the goods train = (4 × 60) km = 240 km.
