A car covers a distance of 350 km in 5 hours and covers another 450 km at a speed of 90 km/h
Formula used:
Average speed = Total distance/ Total time
Calculation
Total distance covered = 350 km + 450 km = 800 km
Total time = 5 hour + 5 hour = 10 hours
Average speed = Total distance/ Total time
Average speed = 800/10 = 80 km/hr
His average speed for the whole journey is 80 km/hr.
