A bus covers the first 50 km of its journey in 95 min and covers the remaining 70 km in 85 min. What is the average speed of the bus?

Correct option is A

Given:

Distance 1 = 50 km, Time 1 = 95 minutes

Distance 2 = 70 km, Time 2 = 85 minutes

Formula Used:

​$$\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}$$​

Solution:
Total distance = 50 + 70 = 120 km
Total time = 95 + 85 = 180 minutes =$$\frac{180}{60}$$​ = 3 hours

Average Speed =$$\frac{120}{3} = 40 \text{ km/h}$$​
