After 2 1/2 days the johnsons had used 2 2/3 tanks of gas how many tanks of gas were they using per day

See explanation

Step-by-step explanation:

According to the question, Johnson used 2 2/3 tanks of gas in 2 1/2 days Thus;

If 8/3 tanks of gas were used in 5/2 days,

Then in 1 day , 5/2 × 3/8 = 15/16 or 0.9 tanks were used per day

- "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."

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
