Answer:
BC = 4.5 (1 dp)
Step-by-step explanation:
<u>Pythagoras’ Theorem</u>

(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
- a = AC = 1.5
- b = AB = 4.2
- c = BC
Substituting these into the formula and solving for BC:




As distance is positive,
⇒ BC = 4.5 (1 dp)

Answer:
x greater than or equal to 4
Average rate = distance / time
distance = average rate x time
Range of distance = 2.2(1) to 2.2(3) = 2.2 to 6.6
Required range is all real numbers from 2.2 to 6.6, inclusive.
