Question

Help with this please i dont really get it

Answer 1

a) 3/5 or .6 km/hr

b) 9/4 or 2.25 km/hr

c) -2/1 or 2 km/hr

Explanation:

the speed refers to the rate of change (or slope) of the segment

so we can use the slope formula: m =
`(y-y)/(x-x)`

AB = (3-0)/(5-0) = 3/5

CD = (12-3)/(12-8) = 9/4

EF = (12-0)/(14-20) = 12/-6 or -2/1
