Give the step-by-step reasoning process and then the final answer. Damien jogs 5 miles per day on weekdays only. How many miles does he run over three weeks?
Three weeks at 5 days per week means Damien runs 3 * 5 = 15 times in three weeks. If each time he runs 5 miles, then over 15 running days he covers 5 * 15 = 75 miles.
The final answer: 75.
