A student wrote four statements during math class. Which statement contains an error? If Iesha traveled at an average speed of 38 miles per hour for 18 hours, she traveled 684 miles. If Jason traveled at an average speed of 46 miles per hour for 16 hours, he traveled 736 miles. If Charmaine traveled at an average speed of 54 miles per hour for 14 hours, she traveled 766 miles. If Raphael traveled at an average speed of 68 miles per hour for 12 hours, he traveled 816 miles.

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.
