To find the total number of miles Josh bikes in one year, we need to multiply the number of miles he bikes in a month by the number of months in a year.
- Number of miles biked per month: 135 miles
- Number of months in one year: 12 months
Now we can set up the multiplication:
\[ \text{Total miles in one year} = \text{Miles per month} \times \text{Months in one year} \]
Substituting the values:
\[ \text{Total miles in one year} = 135 \text{ miles/month} \times 12 \text{ months} \]
Now we will perform the multiplication:
\[ 135 \times 12 \]
To calculate \(135 \times 12\), we can break it down:
\[ 135 \times 12 = 135 \times (10 + 2) = 135 \times 10 + 135 \times 2 \]
Now calculate each part:
\[ 135 \times 10 = 1350 \] \[ 135 \times 2 = 270 \]
Now add the two results together:
\[ 1350 + 270 = 1620 \]
Thus, the total number of miles Josh bikes in one year is:
\[ \boxed{1620} \text{ miles} \]
