Answer:

0.93 minute

Step-by-step explanation:

During the first week:

Kim ran = 1 mile

Duration for this distance = 1 minute

In the second week:

The distance covered by Kim = 1 mile

The time taken by Kim = 7% less compared to the first week

                         = 1 min - 0.07 min = 0.93 minute

<pSo, she completed 1 mile in 0.93 minute this week.
