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?

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?
