A plane flew from Frankfurt to Hong Kong. The flight time was 10hours 45minutes. The average speed was 852km/h. Work out the distance the plane flew.

Approaching this question, I firstly begin by reading the question carefully and determining what it is that needs to be calculated. The next stage is writing down any important information stated in the question which is going to be of use when calculating the answer. The important information for this question is the time taken for travel and the speed at which the plane is travelling at. It is important to clearly write out this also providing the units given. At this point it is important to look ahead at the units that are provided for the answer space in the question which would allow any necessary ammendments to be made. Since time is given in hours and minutes, this is converted completely into hours, 10hours mins = 10.75hours. Since speed = 852km/h and the answer is required to be given in km, at this point all the relevant information is in the correct units. Using the speed = distance/time equation, this can be rearranged to given distance=speed x time. This equation can now be used to give us the required distance travelled, the answer to the question. Then a simple multliplication follows, where distance = 852 x 10.75 = 9159km. This calculation can be performed on a calculator, since a question of this type would appear on a calculator assisted paper.
