Question

Limited time, please answer in 5 minutes. A cross-country skier skied at a rate of 10.82 miles per hour. In 2.45 hours, the skier covered 2.6509 miles. Is this correct? Explain why or why not.

Answer 1

Sample Response: No, the estimate of 11 × 2 = 22 tells us that 2.6509 is too small and the decimal point is placed incorrectly. The product has four decimal places and should have been 26.5090, but a missing zero on the end caused the decimal to end up in the wrong position.

Answer 2

10.82 mph

2.45 hours

10.82*2.45 = 26.509

If you go 10.82 miles per hour, and you are traveling for 2.45 hours, you will go 26.509 miles.

The statement is incorrect.
