12 mph and 16 mph
Step-by-step explanation:
distance = speed * time
56 = s * 2 + (s - 4) * 2
56 = 2s + 2s - 8
56 = 4s - 8
64 = 4s
16 = s
s = 16
s - 4 = 12

Answer:
A(t) = 5000(1 +.05/4)^(4t)
Step-by-step explanation:
The compound interest formula is ...
A = P(1 +r/n)^(nt)
where principal P earns interest at annual rate r compounded n times per year for t years. The problem statement tells you P=5000, r=0.05, n=4. Putting these values into the formula gives ...
A(t) = 5000(1 +0.05/4)^(4t)
