I've been stuck on this for so long and i have an exam soon, anybody who can me : '( ?
a light aircraft flew from maseru to nata and returned to maseru.
the distance from maseru to nata is 1080km.
(i) on the outward flight, the average speed of the aircraft was x km/h. write down an expression in terms of x, for the time taken in hours.
(ii) on the return flight the average speed was 30km/h greater than the average speed of the outward flight. write down an expression in terms of x, for the time taken in hours for the return flight.
(a) the time taken on the return flight was half an hour less than the time on the outward flight. form an equation in x and show that it reduces to x^2+30x-64800=0
(b) solution to the given quadratic equation ^^
(c) the time taken in hours on the outward flight.
(d) the average speed for the whole flight from maseru to nata and back to maseru.
