Mr. Bishop and his family leave on a car trip Saturday morning at 5am and arrive at their destination at 11am. When he began the trip the car's odometer read 44 520 km and when he arrived it read 45 000 km. What was the average speed for the trip?

Average speed =80km/h

Step-by-step explanation:

Given data

initial odometer reading= 44 520 km

final odometer reading= 45 000 km

distance covered= final odometer reading-initial odometer reading

distance covered= 45 000 -44 520

distance covered=480km

time taken = 11-5= 6hours

we know that speed= distance /time

speed=480/6

speed= 80km/h

the answer is 1/4

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
