    The homework

    Slide 4 - Slide

    Rearranging the formula for speed

    Slide 5 - Slide

    The formula for speed
    Speed=timedistance
    v=td
    • speed (v) – m/s
    • distance (d) – m
    •  time (t) – s

    Exercise
    Two friends go on a road trip for three days. 
    On the first day they travel 765 km in 8,5 hours.
    On the second day they travel 660 km in 6 hours.
    On the third day they travel 630 km in 9 hours.

    Calculate their average speed.
