Find the average speed for the journey:

jonas drives 70km in 45 min and then another 120km in 1 hour.

  • Math - ,

    70*3/4 + 120*1
    above is the distance travelled in 1.75 hours (1 hour, 45 minutes.) if we want the average speed, we want it 'per 1 hour'.

    to get this, we divide the above answer(172.5 km) by 1.75. This gives us:
    98.57km/h
