A car of mass 1200 kg travels a distance of d d\,d metres up a straight hill inclined at an angle θ \theta\,θ to the horizontal, where sin⁡θ=115\displaystyle \sin \theta = \frac{1}{15}sinθ=151​.

The work done against gravity as the car climbs this distance is 78.4 kJ.

Taking g=9.8 m/s2g = 9.8\text{ m/s}^2g=9.8 m/s2, find the value of ddd.
