Iwill give brainliest to whoever answers correctly ! a train travels 62 kilometers in 1 hours, and then 52 kilometers in 4 hours. what is its average speed?

52 kilometers in 4 hours = 52 x 4 = 208 km in 4 hours

Total of 5 hours = 208 km + 62 km = 270 km

Average speed = 270 km / 5 hours = 54 km per hour

Answer

54 km per hour

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
