Answer:
It will take 28 hours for Mrs. Chandler to catch up with Mr. Chandler.
Step-by-step explanation:
Given that:
Speed of Mr. Chandler = 70 mph
Distance covered in 4 hours = 70 * 4 = 280 miles
Let,
h be the number of hours.
y be the total distance covered.
y = 70h + 280
Speed of Mrs. Chandler = 80 mph
y = 80h
For catching up, the distance would be same.
80h = 70h + 280
80h - 70h = 280
10h = 280
Dividing both sides by 10
Hence,
It will take 28 hours for Mrs. Chandler to catch up with Mr. Chandler.
Answer:
the diameter will be D=26 in.
Step-by-step explanation:
The area of a circle is given by:
(1)
Where:
- A is the area
- R is the radius of the circle
Now, we know that A = 169 π in²
So, we just need to use equation 1 to find R.
Therefore, the diameter will be D=2*R=26 in.
I hope it helps you!
