Answer:
60 mph
Step-by-step explanation:
Distance by car = 130 mi
Distance by plane = 690 mi
Total travel time = 6 h
R(p) = 3R(c)
The total travel time can be described by the following equation:
[tex]\frac{130}{R(c)}+ \frac{690}{3R(c)}=6\\ 6R(c) = 130 +230\\R(c) = 60\ mph[/tex]
The rate of the car was 60 mph.
