Option 1: 500 m
Option 2: 35 km
Option 3: 40 km
Option 4: 300 m
Correct Answer: 40 km
Solution :
Amit and Sumit start walking from the same point in opposite directions at speeds of 6 km/hr and 4 km/hr, respectively.
Their relative speed = 6 + 4 = 10 km/hr
So, in 4 hours, they will travel = 4 × 10 = 40 km
Hence, the correct answer is 40 km.
