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!
