Mai and tyler were standing at one corner of a large triangular field and decided to race to the opposite corner. since mai had a bike and tyler did not, they thought it would be a fairer race if mai rode along the sidewalk that surrounds the field while tyler ran the shorter distance directly across the field. the field is 100 meters long and 80 meters wide. tyler can run at around 5 meters per second, and mai can ride her bike around 7.5 meters per second.
