Teacher Gene road her bicycle from school and went north for 700m. She turned west for 300m and then southwest for 400m
and reached her destination. The whole trip took about 30 minutes and 11 seconds. Teacher Tanya found a shortcut from

to point your arrows and tell me how long each arrow.
a.

i. Teacher Gene
ii. Teacher Tanya
c.
Find the average velocity (m/s) of:
i. Teacher Gene
ii. Teacher Tanya
7.

10. Find the average velocity if a car started 225m south of town and then ended its journey 2000m south of town in 23.5
minutes.
11. A football player was practicing sprints of 400m. His time was 40 seconds. What is his speed?
12. The same football player came again and ran the same distance, but this time, he ran it in 34 seconds. What is his average
speed now?
13. Jenny doesn’t like running. She walked her 2 mile run for PE class in 30 minutes and 33 seconds. Calculate her average
speed in mi/hr.
14. Sera likes to play with her echo. She likes to stand in tunnels and shout through it to hear her voice come back to her. If the
sound of her voice travels at 335m/s and it takes 30 seconds for her to hear her echo, how far is she from the end of tunnel?
15. Vincent hates taking his time during PE. He likes to run fast. If he runs at a speed of 20 m/s for his 1600m run, how long
would it take him to finish?
