Answer:
I thought this was going to be easy been sitting here for 20min
Can't see the table but direct variation is: y = kx
So if the output is some constant multiple which could be positive, negative or fraction then yes it is direct variation. So just divide a couple y/x = k to see what you get.
For every 10hrs of training you have 200$ increase.
Then for each hour, it will be $20.
Answer:
answers and work are shown below:)
Step-by-step explanation:
Visualize one train going north and the other going south. To determine their distance apart, we could add the distance one train travels north to the distance that the other train travels south.
Thus, |62 kph * t| + |68 kph * t] = 455 km (Seems that you may be mixing km with miles; can't do that; choose one or the other.)
Then
455 km
------------------------ = t = 3.5 hours
(62 kph + 68 kph)
