Answer:
1.08 miles
Explanation:
Given: They jog a total of 20 4/25 miles in a week.
Therefore they jog (20 4/25)/7 = 2.88 miles a day.
If x is how many miles they jog in the morning, they jog 3/5x miles in the afternoon. So 1.6x = 2.88. Divide 1.6 on both sides to get x = 1.8.
1.8 * 3/5 = 1.08 miles
