To find how many miles Mr. Arnold drives in 60 work days, we first need to calculate his daily driving distance and then multiply that by the number of work days.
- Daily round trip mileage: 130 miles
- Work days: 60
The total distance can be calculated as follows:
\[ \text{Total miles} = \text{Daily mileage} \times \text{Number of work days} = 130 , \text{miles} \times 60 , \text{days} \]
Now, performing the multiplication:
\[ 130 \times 60 = 7,800 \]
Thus, the total distance Mr. Arnold drives in 60 work days is 7,800 miles.
The correct option from your list is:
130 x 60 = 7,800 miles.
