- A42
- B108
- C54
- D60
Solution & Step-by-step Explanation
The formula for average speed is:
Average Speed=
Total Time
Total Distance
Given parameters:
Distance covered in the first hour = 75km, Time = 1hour
Distance covered in the second hour = 33km, Time = 1hour
Total Distance=75+33=108km
Total Time=1+1=2hours
Average Speed=
2
108
=54km/h
Average Speed=
