Using the following differential pay scale, calculate the gross wages of the following workers. Units Produced Amount per Unit Employee Units produced From 1-50 55 A. Frank 195 From 51-100 65 B. Clara 200 From 101-200 72 C. Alice 96 More than 200 95 D. Bob 225

- "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."
