# If Brendan drove 4 miles in 8 hours, how many miles did he drive in 3 hours?

He drove in $1 \frac{1}{2}$ miles in $3$ hours.
As Brendan drove $4$ miles in $8$ hours, he drove in one hour $\frac{4}{8} = \frac{1}{2}$ miles.
Hence in $3$ hours, he drove in $\frac{1}{2} \times 3 = \frac{3}{2} = 1 \frac{1}{2}$ miles.
