A student wrote four statements during math class. Which statement contains an error?

Question

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.

Answer 1

To find which statement contains an error, we can calculate the distance traveled for each statement using the formula:

Distance = Speed × Time

1. Iesha:

   • Speed = 38 miles/hour
   • Time = 18 hours
   • Distance = 38 miles/hour × 18 hours = 684 miles (correct)

2. Jason:

   • Speed = 46 miles/hour
   • Time = 16 hours
   • Distance = 46 miles/hour × 16 hours = 736 miles (correct)

3. Charmaine:

   • Speed = 54 miles/hour
   • Time = 14 hours
   • Distance = 54 miles/hour × 14 hours = 756 miles (incorrect, statement says 766 miles)

4. Raphael:

   • Speed = 68 miles/hour
   • Time = 12 hours
   • Distance = 68 miles/hour × 12 hours = 816 miles (correct)

The statement containing the error is Charmaine's statement, where she is said to have traveled 766 miles instead of the correct 756 miles.
