<span>So basically you drove 1/2 hour at 100 km/h which works out to a total travel distance of 50 km (you multiply a 1/2 by 100)
Then you drove for 3/4 hour at 80 Km/h which works out to a total travel distance of 60 km (multiply 3/4 by 80)
now you know that you traveled a total of 110 km
now add up all the times 30 + 15 + 45 = 90 minutes or 1.5 hours
now you know that you traveled a total of 110 km in 1.5 hours
so your average speed is 73.33 km/h for the entire trip</span>
