Aplane flew for six hours. for two hours the average speed was 264mph. for four hours the average speed was 490mph. how far did the plane travel in six hours?

  2488 miles

Step-by-step explanation:

The relevant relationship is ...

  distance = speed × time

For each leg ...

  distance 1 = (264 mi/h) × (2 h) = 528 mi

  distance 2 = (490 mi/h) × (4 h) = 1960 mi

Then the total distance traveled in the 6 hours is ...

  distance traveled = distance 1 + distance 2 = 528 mi + 1960 mi

  distance traveled = 2488 mi

6 1/2

Step-by-step explanation:

Use LCD and evaluate.
