Galois drove 40kilometers due west in 9hours and then drove 62kilometers due north in 5 hours.

What was his dispacement?

What was his average velocity?

  • physics - ,

    Displacement d =sqrt(s1² + s2)²) =
    =sqrt (40² +62²) =73.8 km.
    Average velocity
    V(ave) = d/t = 73.2/14 =5.3 km/hr.
    Note!
    Average speed is (40+62)/14 =7.3 km/hr

    Awsome thank you. Now I've been trying to figure out how far he traveled but my equation keeps giving me the wrong answer. How would I figure this out?
