Answer:
25.7minutes
Step-by-step explanation:
D =r×t=2×1.5=3miles
A D=7÷2=3.5
7=1h. 3.5=30minutes.
3.5=30
0.5=x
3.5x÷3.5=15÷3.5
X=4.3
(3.5-0.5)=(30-4.3)
Hence it takes Amanda 25.7minutes to catch up with Ben.
Answer:

Step-by-step explanation:
The time constant of the element X is:


The decay function has the following form:




7s + 20 = 4s -13
7s - 4s = -13 -20
3s = -33
s = -33/3
s = -11
In order to solve this problem, you must draw a right triangle first to help you visualize the path of the jogger.
You are given 0.5 miles north (which will be the height of the right triangle), and 1.3 miles (which will be the hypotenuse of the triangle).
Using Pythagorean Theorem: a²+b²=c², we have:
0.5² + b² = 1.3²
b = 1.3²-0.5²
b = 1.2 miles
