Two chefs are trying to break the world's record for the longest strand of spaghetti. chef a measures his spaghetti strand to be 503 2/3 ft. chef b measures his spaghetti strand to be 503.7, the judges declare chef b the winner. explain why chef a should protest the judge's decision.

- "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."

you a real one for tat answer
