Buses leave city a and city b every 10 minutes during the morning, repeating the two journeys shown on your graph. on your graph draw a line to show the bus that leaves city a at 0920. how many buses traveling in the opposite direction will this bus meet before it reaches city b?

In every 10 minutes it is repeated by 2 journeys on the opposite sides

3x2=6 :)

Step-by-step explanation:

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
