Answer:
4-
-
Step-by-step explanation:
To find your average speed, divide 180 by 4 which is 45.
Formula:
Plug the number into the equation
180 is d (distance)
4 is t (time
So it would be 180=r•4
1) get r by itself so divide 4 to both sides
2) 180/4 = r
3) 45 = r
Distance from the boat to the town:
d² = 2.2² + 16.8²
d² = 4.84 + 282.24
d² = 287.08
d = √287.08
d = 16.9434 ≈ 16.9 km
