Answer:

$S = 149\ min$

$S = 2\ hr\ 29\ min$

Step-by-step explanation:

Let S be the sum of the times for all winning team.

Given:

leg 1. 32 minutes 56 seconds.

leg 2. 42 minutes 28 seconds.

leg 3. 34 minutes 34 seconds.

leg 4. 39 minutes 2 seconds

We need to find the total time to run all four legs of the marathon.

Solution:

Sum of the times for all winning team.

$Sum\ of\ the\ times = leg\ 1 + leg\ 2 + leg\ 3 + leg\ 4$

Substitute running times for all legs.

$S = 32\ min\ 56\ sec+ 42\ min\ 28\ sec + 34\ min\ 34\ sec + 39\ min\ 2\ sec$

Now, we write the minutes and seconds separately.

$S = (32+42+34+39)min+(56+28+34+2)sec$

$S = (147)min+(120)sec$

$120\ sec =\frac{120}{60} = 2\ min$

$S = (147)min+(2)min$

$S = 149\ min$

Therefore, Total time taken by all four legs $S = 149\ min$ or $S = 2\ hr\ 29\ min$ .

I need help with this

kipiarov [429]

Answer:

Step-by-step explanation:

((((((.5 mile = .25 hour<<<<<<<<<<<<<<<<<<<<<<<<<<

Multiply both sides by 4, because there are 4 quarters in 1 hour

(4)(.5) = (.25)(4)

2 miles =1 hr

Multiply both sides of the original equation by 3 to figure out how far in 3/4 of an hour

(3)(.5) = (3)(.25)

1.5 miles = 3/4 of an hour

now add the two answers together to figure out that the person walked 3.5 miles in 1 3/4 hours

***You also could have multiplied both sides of the original equation by 7, recognizing that that there are 7 quarters in 1.75 hours.
