A long distance that I have started on a course at average speed of nine my para half an hour later a second round pick in the same course as an average speed of 11 mph how long after the second runner starts well the second runner overtake the first runner

t = 2.25 hrs

Step-by-step explanation:

Given:

- The first runner speed v1 =  9 mph

- The second runner speed v2 = 11 mph

- Second runner starts half an hour later than first

Find:

how long after the second runner starts well the second runner overtake the first runner

Solution:

- The time taken by second runner = t

- Distance traveled by first runner d is as follows:

                            d = 9* ( t + 0.5 )

- Distance travelled by second runner d is as follows:

                            d = 11*t

- Since the distance covered d is same for both runners then we equate the two expressions:

                            11*t = 9*t + 4.5

                            3*t = 4.5

                             t = 2.25 hrs

- They will meet after 2.75 hrs after first runner starts race.

step-by-step explanation:

this woman was an important writer and propagandist during the american revolution. she was a member of the committee of correspondence (in fact the committee was formed in her home) and was an advisor to many of the revolutionary leaders, including george washington and john adams. who was this revolutionary woman?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
