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 - 0.2 * 50 minutes
= 50 minutes - 10 minutes
= 40 minutes
This year, it takes her 40 minutes to run 5 miles
15 thirds divided by 3 = 1.66666667
Part 1: m = ( 2•3 ) + 3
Part 2: 9 miles
Add all the miles together
2+2+2= 6+ 3 =9
the volume is 6×6×x=252
so 252/36=x
x=7
15%
1.00-.85=15%
