Use the Distance Formula to find the distance between the pair of points. Round to the nearest tenth if necessary. W(2, 5), U(4, 3)

Solution:

Given that,

Points are W(2, 5), U(4, 3)

Distance between two points is given as:

From given,

Substituting the values we get,

Thus the distance between the pair of points is 2.8 units

astronomers is your final answer! : )

- "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."
