If the amount of time taken to go said distance is x and the amount of time taken to go back said distance is y, then the amount of miles total is 7x+3y due to that for every hour, she adds 7 miles when going there and 3 miles for walking back. In addition, since the total amount of time is 4 hours, x+y=4 as the total time spent as well as 7x=3y due to that they're the same distance.
x+y=4
7x=3y
Dividing the second equation by 7, we get x=3y/7. Plugging that into the first equation, we get 3y/7+y=4=10y/7 (since y=7y/7). Multiplying both sides by 7 and then dividing both by 10, we get 28/10=2.8=y in hours. Since 0.1 hours is 60/10=6 minutes, and 0.8/0.1=8, 6*8=48 minutes=0.8 hours, meaning that she should plan to spend 2 hours and 48 minutes walking back

Answer:
190 is 76% of 250
Step-by-step explanation:
We have, 76% × x = 190
Multiplying both sides by 100 and dividing both sides by 76,
we have x = 190 × 100/76
x = 250
If you are using a calculator, simply enter 190×100÷76, which will give you the answer.
Answer:
Step-by-step explanation:
Least to largest:
First compare the whole parts of the decimal number. The whole part with greater number will be the greatest number.
2) Then compare the decimal parts. Compare tenth place. The decimal number that has greater number in the tenth place will be greater.
3) If the number in tenth place is equal, then compare 100th place and so on
