A jet heads 60° north of east at 700 miles per hour. When the jet reaches a certain point, it encounters
a wind blowing due east at 100 miles per hour. What is the resultant speed of the jet?

Respuesta :

From the given triangle,

opposite side = 100 mph

Adjacent side = 700 mph

To find the value of resultant speed,

by Pythagoras theorem,

Resultant speed is,

[tex]\begin{gathered} R^2_s=(100)^2+(700)^2 \\ R_s\text{ }=\sqrt[]{500000} \\ =707.1 \\ \approx707 \end{gathered}[/tex]

The resultant speed is 707 mph

The correct answer is the fourth option
