A bus traveling at an average rate of 30 miles per hour left the city at 11:45 a. m. A car following the bus at 45 miles per hour left the city at noon. At what time did the car catch up with the bus

  12:30 p.m.

Step-by-step explanation:

The bus got a 1/4-hour head start, so was (1/4 h)(30 mi/h) = 7.5 mi away when the car started. The car's speed was 45-30 = 15 mi/h faster than that of the bus, so closed the distance in ...

  (7.5 mi)/(15 mi/h) = 1/2 h

Half an hour after the car started, the time was 12:30 p.m.

The car caught up at 12:30 p.m..

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
