A plane 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?
1 answer:
Answer:
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
