Question

Marlene rides her bicycle to her friend Jon's house and returns home by the same route. Marlene ride her bike at constant speeds of 9 mph on level ground, 6 mph going uphill and 18 going downhill. If her total riding time was 2 hrs, how far is it to Jon's house.

Answer 1

The correct answer would be 99 miles. This will be done using the formula: distance = rate (miles) X time (hours). In this case, D= (9+6+18) X 2. So the answer is 99 miles. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
