Answer:
40 minutes
Step-by-step explanation:
Last year she ran five miles in 50 minutes
This year her timing improved by 20%. This means she runs 5 miles in 20% less time than last year
How long does it take her to run five miles?
= 50 minutes - 20% of 50 minutes
= 50 minutes - 20/100 * 50 minutes

= 50 minutes - 10 minutes
= 40 minutes
This year, it takes her 40 minutes to run 5 miles
