Correct Answer - Option 1 : 3 PM
Distance between bhilai and manmad = 465 km
Relative speed = S1 + S2…………….(opposite direction)
Distance covered by car leaving from Bhilai = 65 km/hr x 1 hr = 65 km
Distance left = 465 – 65 = 400 km
Now, the car from Manmad also gets moving and both are moving towards each other.
Applying the formula for relative speed,
Relative speed = 65 + 35 = 100 km/hr
Time required by the carsto meet = 400/100 = 4 hours
Thus, the cars meet at 4 hours after 11 AM, i.e., 3 PM.
∴ The cars will meet at 3PM.
