Question

Abdul's average speed is 20 mph in heavy traffic, and his average speed is 50 mph in light traffic. If he was in heavy traffic for 1 hour and light traffic for 3 hours, how far did Abdul travel?

Answer 1

Be careful as StudyIsland/Edmentum will change up a few numbers on you.

In my case: 3 was changed for 2.

Its 20 mph x 1 hr = 20

Then 50 mph x 2hr = 100

Add both and answer is: 120

Just took test.

Answer 2

20x1+50x3 = 170 MPH

Explanation:

Therefore, he traveled 170 mph
