Question 1153889
<br>
The distances are the same; the ratio of the speeds is 10:2 = 5:1.<br>
That means the ratio of times is 1:5.<br>
That means the time spent running is 1/6 of the total time and the time spent walking back is 5/6 of the total time.<br>
ANSWER: Time spent walking back = 5/6 of 3 hours = 2.5 hours.<br>
