Answer:
$17.35/h
Step-by-step explanation:
In order to get the amount per hour he made, you first need to calculate the global amount of money he made.
He was paid $2,900 then he had costs of $1,200, that leaves him a net income of $1,700 ($2,900 - $1,200)
Then he worked a total of 98 hours for that money.
A salary is an amount of money expressed by a period of time. In this case, we'll use hours.
So, Jonah earned $1,700 after 98 hours of work:
S = $1,700 / 98 hours = $17.35/h
For this case we have:
If after 2 hours the marathon runner has traveled 22 kilometers we have:
2h -----------> 22km
Applying a rule of three, we can know the time it takes to run 42km. So, we have:
2h -----------> 22km
x -------------> 42km
Where "x" is the time it takes to travel 42km. Resolving we have:
Thus, after 3.82 hours the marathon runner will travel 42km.
Answer:
3.82 hours
