Find the average speed of Sanjay, who covers the first 150 km in 4 hours and the next 250 km in another 4 hours.

Correct option is C

Given:
First distance = 150 km in 4 hours
Second distance = 250 km in 4 hours
Formula Used:
​$$\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}$$​​
Solution:
Total Distance = 150 km + 250 km = 400 km
Total Time = 4 hours + 4 hours = 8 hours
Average Speed = $$\frac {400}{8}$$​ = 50 km/h
