Todd swam 10 laps around the pool and walked on the treadmill a total of 5.2 miles. It took him 2.3 minutes to swim each lap and 45.4 minutes to work on the treadmill. How long did it take him to swim and walk?

Step-by-step explanation:

Was so she just wanted

23 minutes in the pool

Step-by-step explanation:

if x = 1, then the answer is 3.5

- "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."
