Ok, seriously, if you're in college and asking this you're seriously not smart.
Everytime Amber goes running she runs 1 mile.
She runs 4 times each week. How many miles does she run in one week.
Number of mile(s) ran in one session = 1 mile.
Number of running sessions in a single week = 4
Total distance covered = 1 x 4 = 4 miles.
