Leslie ran 3 mile race. The second mile took her 10 percent longer than the first one and the third mile took her 24 seconds lon
Brilliant_brown [7]

Answer:

8.8 Minutes or 528 Second.

Step-by-step explanation:

↓[ Read Below ]↓

Important Info:

Leslie Ran 3 Mile Race.

2nd Mile = 10% longer than 1st and 3rd Miles took her 24s longer than 2nd Mile

Question to Answer:

Leslie’s total time for the race was 26 minutes how long did the second mile take her?

Explanation/Solution:

Let for first mile, she took x minutes . And second mile took her 10 percent longer, so second mile took

x+ 10/100x = 110/100x=1.1x

And the third mile took 24 seconds longer as compared to second mile .

So third mile took

1.1x+24/60 = (1.1x+0.4) Minutes

And the total time for the race was 26 minutes, that is

x+1.1x+1.1x+0.4=26

3.2x=26-0.4

3.2x=25.6

x= 25.6/3.2 = 8 Minutes

So the first mile took 8 minutes. And therefore second mile took

= 1.1 (8) = 8.8 Minutes

Also Equal to 528 Second.

frez [133]

Step-by-step explanation:

This is the answer because if you divide 160 divide by 5 that gives you 32 for the roast beef. For the turkey you divide 160 and 3 that gives you 80. For the vegetarian you have to add 32 and 80 that gives you 112. Then, you subtract 160 and 112 that gives you 48. To check your answer you add 32, 80, and 48 that gives you 160.
