Problema Solution
Marie rode her bicycle from her home to the bicycle shope in town and
then walked back home. If she averaged 6 miles per hour riding and 3
miles per hour walking, how far is it from her home to the bicycle shop if
her total travel time was 1 hour?
Answer provided by our tutors
If the distance from home to the bicycle shop is d miles, then time taken while riding to town = d/6 hour
and time taken to walk back home = d/3 hour
Total time = d/6 + d/3 = 3d/6 = d/2 hours
Now, d/2 = 1
d = 2
So, distance = 2 miles
