Steve traveled the first 2 hours of his journey at 40km/h and the last 3 hours of his journey at 80km/h. What is his average speed of travel for the entire journey?

    2 hours = 80 km
    3 hours = 240 km

    5 hours = 320 km

    320 / 5 = ______ km/h

    So then would i change 64km/h into meters/seconds

  • gr 11 physics -

    Why is 2 hours equal to 80km

  • gr 11 physics -

    2 hours * 40 km/h = 80 km

    Does your problem ask you to change kh/h to m/s?
