(40 points) Add the given vectors ⃗ and ⃗⃗, and calculate the magnitude and the angle of the resultant ⃗⃗. ⃗ = 54 at an angle of α = 100° ⃗⃗ = 42 at an angle of β = 200°

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
