GIVING BRAINLIEST!

Mathematics
1 answer:
slega [8]3 years ago
8 0

Answer:

b. 200/x

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

First half speed= x

Second half speed= 1.5 x (1.5 times faster on the second 120 miles of his trip)

Since:

Time = distance /speed  

Total time = 1st half time + 2nd half time

Replacing with the values given

Total time =120/ x + 120/1.5x

Total time = 180/ 1.5x + 120 /1.5x

Total time = 180+120/1.5x

Total time = 300/1.5x = 200/x

Feel free to ask for more if needed or if you did not understand something.

3. Laura walks 3/5 mile to school each day. Isaiah walk to school is 3 times as long as Laura's. Howfar does Isaiah walk to scho
Finger [1]
Lets write down what we know...

Laura walks 3/5 mile to school everyday

Laura=3/5mile

Isaiah's walk is 3 times as long as Lauras, so

Isaiah=Laura*3

We know how far Lauras walk is so we can solve for Isaiah's walk

Isaiah=3/5*3 (or Isaiah=3/5+3/5+3/5 if thats easier for you to solve for)
Isaiah=9/5 miles

Now we know the answer! Great, Isaiah walks 9/5 miles to school each day. But 9/5 is an improper fraction, so lets convert it to a mixed number.

9/5=

To solve for this, we have to find out how many times 5 can go into 9. 5 goes into 9 one time with a remainder of 4, so we can write the mixed number as.

9/5= 1 4/5

Isaiah walks 9/5miles or 1 4/5 miles. Both are correct.
