Answer:

1 dollar every 1/39 hour

Step-by-step explanation:

If Christopher earns $78 in two hours, he must earn $39 dollars in one hour because 78/2 is 39. Therefore, every hour Christopher earns $39. To find the amount of hours per dollar, divide 1, the hour, by 39, the money per hour, to get 1/39.

Answer:

1 hour/39 dollars

Step-by-step explanation:

So we need to find the unit rate in hours per dollar

Lets replace per with a division sign

We know that 2hours=$78

So we can divide 2 and 78 to get unit rate

78/2=1/39

1 hour/$39

Hope this helps!
