Correct Answer:
10 seconds
10 सेकंड
Distance between Vinay and Mahesh = 250 meters
Speed of Vinay = 36 km/hr = = 10 m/s
Speed of Mahesh = 54 km/hr = = 15 m/s
Relative speed of vinay and mahesh as they are running towards each other = 10 + 15 = 25 m/s
Now time taken until they meet each other = = 10 seconds
विनय तथा महेश के बीच की दूरी = 250 meters
विनय की चाल = 36 km/hr = = 10 m/s
महेश की चाल = 54 km/hr = = 15 m/s
विनय तथा महेश की सापेक्ष चाल जब वो एक-दूसरे की ओर चल रहे हैं = 10 + 15 = 25 m/s
एक-दूसरे से मिलने में लगा समय = = 10 सेकंड
