Answer:
$5
Step-by-step explanation:
(5/6)*24=20
20-15=5
2 over 3 is 14 over 21 simplified, dividing both numbers by 7.
D/7.29 = 1.5/4.05
d = (1.5/4.05)7.29 = 2.7
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
