Shanice left the science museum and drove toward the train station. Jack left two hours later driving at 30km/h in an effort to catch up to Shanice. After driving for four hours Jack finally caught up. What was Shanice’s average speed?

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
