Answer:
You can check it by solving it in your head. They are separating at the rate of 55-40 or 15 miles per hour. So in 1 hour or 60 minutes they'll be 15 miles apart, so in 20 minutes they'll be 5 miles apart, so in 40 minutes they'll be 10 miles apart. So it has to be 40 minutes.
Step-by-step explanation:
55t-40t=10
15t=10
15t/15=10/15
2/3
40 Minutes
Answer:
Approximately 50.318 km.
Step-by-step explanation:
To find the diameter of a circle, you use the equation C = pi x d, where the d stands for diameter.
First, you'd plug in the 158 for C, so you have 158 = pi x d.
Since we are using 3.14, it would be 158 = 3.14 x d, and so then we'd divide both sides by 3.14 to isolate the variable d.
158/3.14 gives you approximately 50.3184713376, though rounded to the nearest thousandths, 50.318.

Answer: Rate > 12 miles/day
x > 12
She must run more than 12 miles each day
Mona wants to run more than 60 miles this week. She ran a total of 24 miles during the first 4 days of the week. Which number line represents the number of miles Mona must run each day if she wants to meet her goal?
answer choices
x ≥ 10
x = 12
x > 10
x > 12
Step-by-step explanation:
To complete more than 60 miles a week.
After running 24 miles during the first 4 days
We are left with (7-4) days = 3 days
And also,
(60-24) miles to complete the weekly target
> 36 miles (more than 36miles)
Therefore, the number of miles needed to cover per day in the next 3 days is given as.
Rate > distance/time
Rate > 36miles/3days
Rate > 12 miles/day
