0.85 is between 0.8 and 0.9
Since 19 is a prime number it only goes into 1 and 19 so 1 times 19 is the only possible answer
F(x) = g(x) for x = 1 and x = 3. Verify that for yourself.
Answer: 30 mph.
Total speed = S1 + S2
where total speed is
for the average speed goal (60m ph), S1 is the speed for the first mile (30 mph)
and S2 is for speed for the second mile which is unknown. To solve, simply subtract
S1 from total speed.
