Jerry walked a dog from 6:40 am to 7:30 pm one day. If he was paid at the rate of 6$ per hour, how much did he earn that day?

Tom [10]

Answer:

Explanation:

Since Jerry walked the dog from 6:40am to 7:30am, the total minutes that he walked the dog was 50 minutes. Also a note, an hour is 60 minutes.

Since he is paid at a rate of $6 per 60 minutes, we can make a proportion.

660=x50

From here, you have to solve for x. So cross multiply, and then simplify.

60x=50⋅6

60x60=50⋅6/60

x=5⋅6/6

x=5

So the answer is $5.
