After 2 hours, she was (62 mph -50 mph)*2h = 24 miles behind her trip average, so she had to make that distance up in the last 3 hours. That is, her average for the last 3 hours was (24 mi)/(3h) = 8 mph more than her trip average.
Jiamin averaged 62+8 = 70 mph for the last 3 hours of her trip.
The value of x in the segment is 3
<h3>How to determine the value of x?</h3>
Using the secant and segment theorem, we have:
x * (x + 21) = (x + 1) * (x + 1 + 14)
Evaluate the sum
x * (x + 21) = (x + 1) * (x + 15)
Expand
x^2 + 21x = x^2 + 15x + x + 15
Subtract x^2 from both sides
21x = 15x + x + 15
Evaluate the like terms
5x = 15
Divide both sides by 5
x = 3
Hence, the value of x is 3

Answer:
x + 37 ≥ 65
Step-by-step explanation:
Given:
Money Micah wants = $65
Money Micah had = $37
Find:
Money Micah need
Computation:
Money Micah need(x)
x + 37 ≥ 65
So,
Money Micah need = 65 - 37
Money Micah need = $28
