After driving 175 miles in the plains, car travles up a hill at 28 miles/hr. If the total distance covered in the plains and the hill was 273 miles. How much time was taken by the journey in ghe hills?

3.5 hours was taken by the journey in the hills.

Step-by-step explanation:

Total of 273 miles.

In the plains, 175 miles.

The rest(x), on the hills.

So

175 + x = 273

x = 273 - 175

x = 98

98 miles in the hills, at the speed of 28 miles/hr.

To find the time, we can solve a rule of three.

1 hr - 28 miles

x hrs - 98 miles

3.5 hours was taken by the journey in the hills.

16.9 times 2.85

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
