With this question! will mark brainliest riley made a scale drawing of a triangular clock face. riley used a scale factor of 3 when making her drawing. if the base and the height of riley's drawing are 10 centimeters and 15 centimeters respectively, what is the area of the triangular clock face? a. 75 square centimeters b. 225 square centimeters c. 675 square centimeters d. 2,700 square centimeters

step-by-step explanation:

- "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."
