Correct Answer - Option 3 : 75 km/h
Given :
The distance between Bhopal and Indore is 1250 km.
Two buses start from Bhopal and Indore towards each other.
Both buses meet each other after 10 hours.
Bus from Bhopal is 25 km/h faster than the bus from Indore.
Formula used :
Time = distance/speed
Calculations :
Let the speed of the bus from Bhopal be 'B'
Let the speed of the bus from Indore be 'I'
The total distance between cities = 1250 km
Total time = 10 hours
According to the question
The relative speed of the buses = Distance/time
I + B = 1250/10
I + B = 125 ....(1)
B - I = 25 ....(2) (Given)
Now solving both the equations we get,
B = 75 and I = 50
∴ The speed of the bus from Bhopal will be 75 km/h.
