Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 414.

Distances = 1320 km, 1760 km, 2095 km

Speeds = 528 km/h, 352 km/h, 419 km/h

Average speed = Total distance ÷ Total time

Average speed = 1320+1760+20951320528+1760352+2095419\frac{1320 + 1760 + 2095}{\frac{1320}{528} + \frac{1760}{352} + \frac{2095}{419}}  = 5175/12.5 = 414 km/h
