Distance = Speed*Time = 70*5 = 350 miles.
distance = speed X time at speed. Therefore, in this instance, the distance is 3 X 50 + 70 X (1/2) = 185 miles.
About 12 hr 51 minutes (assuming 70 MPH average as stopping for gas will be necessary).
Yes, almost any car can get to 70 mph in 1500 feet.
Low anti-freeze makes a car run hot going 70 mph.
