Answer:

Step-by-step explanation:
It is an acute triangle because none of its angles are equal to (right) or above (obtuse) 90 degrees.
It depends on your fuel economy, how much fuel the car burns per 100 miles etc.
From information given, we know
208 miles was at rate of 65 mph. so divide total mileage by speed to get time spent.
208 ÷ 65 = 3.2 hours
So the rest of the trip took 6 - 3.2 = 2.8hours to travel another 348 total miles minus the 208 miles driven at 65mph is 140 miles.
140 miles divided by 2.8 hours gives speed
140 ÷ 2.8 = 50 miles per hour
