Kim is training for a long-distance marathon. Before training, she was able to run one mile in seven minutes. For each of the next three weeks, she improved her time an average of 7 percent over the previous week. What is her time now?

0.93 minute

Step-by-step explanation:

in first week:

distance traveled by Kim = 1 mile

time taken by Kim = 1 minute

in second week:

Distance traveled by Kim = 1 mile

time taken by Kim = 7% less than the first week

                              = 1 min - 0.07 min = 0.93 minute

Thus, she traveled 1 mile in 0.93 minute in this week.
