A jet plane cruising at 450 miles per hour climbs at an angle measuring 13 degrees. To the nearest tenth of a mile, how much altitude does the jet gain in 5 minutes
In 5 minutes, the plane travels 450/12 = 37.5 miles
And we can use the sine to calculate this
sin13 = a / 37.5 where a is the gain in altitude.........rearrange
37.5(sin13) = a = about 8.4 miles
