A car is travelling up a long 1.1º incline at a constant velocity of 57.6km h^-1. Determine how long it will take to increase its altitude by 20m.

 

[Life'sHard]

Draw a triangle with 20m as height and angle 1.1˚ opposite of 20m. Sin to find the hypotenuse of the triangle which should give the distance travelled. Then convert the velocity into m/s. All you have to do is s=d/t where you know speed and d is the length of hypotenuse.
