A car leaves Town A for Town B, which are 550 km apart, at an average speed of 72 km/h. At the same time, a truck leaves Town B for Town A and travels along
the same road as the car at an average speed of 38 km/h. Find the time taken for the
two vehicles to meet.

Let t = time it takes for them to meet

:

When the two meet, they will have traveled a total of 550km

:

Write a distance equation, dist = speed * time

then

72t = car's dist

38t - truck's dist

:

Car dist + truck dist = 550 km

72t + 38t = 550

Add like terms

110t = 550

t = 550/110

t = 5 hrs

Can i have brainliest?

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

it would open into a square depending on the type of envelope i’m not sure about the second part
