Answer:
Step-by-step explanation:
I don't see the choices, but I will make the equations that seems to be correct to me.
Known facts:
- maintained an average speed of 35 miles per hour (mph) for the first m hours of her road trip.
- next n hours of the trip, she drove at an average speed of 60 mph.
- Eva drove a total of 225 miles in 4.5 hours.
Let's make the equations:
m + n = 4.5
35m + 60n = 225
Hope that helps!

Answer:
Option a:
a=79
b=1.002
r=0.2%
Step-by-step explanation:
Q = 79 (1.002)^t
Q = a b^t = a (1+r)^t
Comparing with the formulas:
a=79
b=1.002
1+r=1.002
Solving for r: Subtrating 1 both sides of the equation:
1+r-1 = 1.002 - 1
r = 0.002
Writting r as percent:
r = (0.002) 100%
r = 0.2%
