Solution

The correct option is C Route B
For route A, displacement and distance covered are equal.
SpeedAvg=Distance coveredTime taken
SpeedAvg=480 km6 hr
SpeedAvg=80 km/hr
For journey through route B, displacement and distance covered are not equal.
SpeedAvg=Distance coveredTime taken
SpeedAvg=720 km8 hr
SpeedAvg=90 km/hr
Hence average speed is higher in case of jouney via route B
