Tan 2° = x / 1 mile, where x is the vertical change 0.03492 = x / 1 mile x = 1 mile · 0.03429 = 0.03492 miles 1 mile = 5,280 feet 0.03492 · 5,280 = 184.38 ft Answer: The vertical change is 184.38 feet
If 3mile=28 min x mile=42 min cross multiply x=3/28 therefore if 3/28=1 min then x mile= 42 min cross multiply 42 x 3/28 =21 x 3/14 =3 x 3/1 =9 The answer is 9 miles
