Answer:

D. 70

Step-by-step explanation:

Distance = k × time

70 = k(1)

k = 70

Distance = 70 × time

time to complete the journey:

420 = 70 × time

time = 420 ÷ 70

time = 6 hours

Answer:

Whoa, that's a lot to answer...

15. 30000=500x

16. y=58x+5

in 16, the total cost is y, so y has to be in 1 side for itself. and we need to add the amount of tickets and the fee (5$). So we get that equation.
