An engineer traveled 130 mi by car and then an additional 690 mi

Reptile [31]

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:

$\frac{130}{R(c)}+ \frac{690}{3R(c)}=6\\ 6R(c) = 130 +230\\R(c) = 60\ mph$

The rate of the car was 60 mph.
