Answer:
$84,330
Step-by-step explanation:
The compound interest formula gives the value of an investment.
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years. Using your given values, we can solve for P.
110,000 = P(1 +0.019/12)^(12·14)
P = 110,000/(1 +0.019/12)^(12·14) ≈ 110,000/1.00158333...^168
P ≈ 110,000/1.30446
P ≈ 84326.04 ≈ 84,330 . . . . dollars

Total miles = 70 + 70 = 140 miles
Total time = 140 miles / 57 mph = 2.456 hours
Time 1: 70 miles / 70 mph = 1 hour
Time 2: 70 miles / x mph
Total time = time 1 + time 2:
2.456 = 1 hour + 70/x
Subtract 1 hour from both sides:
1.456 = 70x
multiply both sides by x:
1.456x = 70
Divide both sides by 1.456:
x = 70/1.456
x = 48.0769 miles per hour
Rounded to 2 dp = 48.08 miles per hour
