If a road has a grade of 30°, this means that it's angle of elevation is 30°. If you travel 1.5 miles on this road, how much ele
vation have you gained in feet (5280 ft = 1 mile)?
1 answer:
The elevation gained after travelling 1.5 miles = 3960 ft.
Step-by-step explanation:
Given data,
Angle of elevation = 30°
Distance traveled= 1.5 miles
1 mile = 5280 ft.
Therefore 1.5 miles = 5280 x 1.5
= 7920 ft.
The height can be calculated by,
sin 30° = height / 7920
1/2 = height / 7920
Height = 7920/2
= 3960 ft.
The elevation gained after travelling 1.5 miles will be 3960 ft.
