Tim records how fast he can run a mile over five consecutive weeks. he records his runs, in minutes, to be 6, 5.6, 5.4, 5.2, and 5. what is the range of tim's times?

The range is 1

Step-by-step explanation:

To calculate range, you subtract the lowest value from the highest value.

The lowest is 5 here and the highest is 6. The range is 6-5 which equals 1.

1

Step-by-step explanation:

You are finding the range, which can be found by subtracting the smallest number from the greatest number.

Smallest number = 5, Greatest number = 6

6 - 5 = 1

1 is your range 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."
