Two planes travel at a constant speed. plane a travels 2,800 miles in 5 hours. plane b travels 3,885 miles in 7 hours. which plane is faster? explain your reasoning

Plane A is faster since it has a better speed than plane B.

Since Plane A travels 2,800 miles in 5 hours, the speed of plane A will be:

= 2800/5

= 560 miles per hour

Since Plane B travels 3,885 miles in 7 hours, the speed of plane B will be:

= 3885 / 7

= 555 miles per hour

Therefore, plane A is faster.

The answer is: Plane A is faster, by 5 miles per hour.

Step-by-step explanation:

Plane A travels 2,800 miles in 5 hours.

Divide to get miles per hour:

2,800 / 5 = 560 mph

Plane B travels 3,885 miles in 7 hours.

Divide to get miles per hour:

3,885 / 7 = 555 mph

Plane A is faster, by 5 miles per hour.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

10 b/c 5*2 =10
