Question

The Boardman family walked two over five of a mile in two over seven of an hour. What is their unit rate in miles per hour? two-sevenths over two-fifths equals one and two-fifths miles per hour two-sevenths over two-fifths equals five over seven mile per hour two-fifths over two-sevenths equals one and two-fifths miles per hour two-fifths over two-sevenths equals five over seven mile per hour

Answer 1

Their unit rate was 1 2/5 miles per hour.

Answer 2

`((2)/(5) \ mi)/((2)/(7) \ h)=(2)/(5) * (7)/(2) \ (mi)/(h)=(7)/(5) \ (mi)/(h)=1 (2)/(5) \ (mi)/(h)`

Their unit rate was 1 2/5 miles per hour.
The correct answer is: "two-fifths over two-sevenths equals one and two-fifths miles per hour".
