Question 1076900: On average, Sherry can travel four times as fast on cross-country skis as she can with snowshoes. To travel 24 km, she needs 6 h more if she is snowshoeing than if she is skiing. What is her average speed on crosscountry skis?

Let n be Sherry's rate on snowshoes. Then her rate on skis is 4n. So:
24/n - 6=24/4n
96-24n=24
n=3
Sherry can travel 3km/h on snowshoes; and 12 km/h on skis. ☺☺☺☺
