Question

Imagine running one hour straight west at 5 km/h and then changing direction quickly and running

one hour straight north at 5 km/h. What was your total displacement? Round to the nearest whole
number.
O 10 km
O 5 km
O 50 km NW
O 7 km NW

Answer 1

If you ran one hour straight west at 5 km/h and then changed direction quickly and ran one hour straight north at 5 km/h, your total displacement would be 7 km NW.

Step-by-step explanation:

This is because your total change in position would be 5 km to the west and 5 km to the north, resulting in a displacement of 7 km NW.

Answer 2

7 km NW

Step-by-step explanation:

After running one hour straight west at 5 km/h and then changing direction quickly and running one hour straight north at 5 km/h, the total displacement would be 7 km NW, rounded to the nearest whole number.
