Error Statement: "If Charmaine traveled at an average speed of 54 miles per hour for 14 hours, she traveled 766 miles"

Step-by-step explanation:

We know D = RT

Where

D is distance

R is rate

T is time

We need to check each statement using this formula.

First Statement Check:

38 * 18 = 684 (correct)

Second Statement Check:

46 * 16 = 736 (correct)

Third Statement Check:

54 * 14 = 756 (incorrect)

Fourth Statement Check:

68 * 12 = 816 (correct)

So, we see the 3rd statement is incorrect, this contains an error.
