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

To determine how much Jerry earned for walking the dog, we first need to calculate the total time he spent walking. He started at 6:40 a.m. and finished at 7:30 a.m.

Calculating the time, we find that from 6:40 to 7:30 is 50 minutes. To convert this into hours for payment calculation, we divide the minutes by 60, which gives us:

50 minutes ÷ 60 minutes/hour = 5/6 hours.

Next, we calculate Jerry's earnings by multiplying the time he worked in hours by his hourly rate of $6.

So, the calculation is as follows:

5/6 hours × $6/hour = $5.00.

It seems like there may have been a miscalculation or oversight regarding the hourly rate, which does not match the answer provided. In fact, the correct earnings based on the given time and rate of pay is $5.00, which is not included in the choices. The closest option that could be mistakenly chosen is $5.90, but it's important to revisit the calculations to confirm the accurate amount earned based on the time worked.
