document.write( "Question 588608: A motorist, X, travelling at a uniform speed of 48 km/h passes a village at 6 a.m.. Another motorist, Y , travellingat a uniform speed of 66 km/h passes the same village at 6.30 a.m. Draw straight line graphs to show the journeys of X and Y between 6.30 a.m. and 9 a.m. , taking 4 cm to represent 1 hour on the time axis and 2 cm to represent 20 km on the the distance axis. Deduce from your graph the time at which both motrists are at the same distance from the village. \n" ); document.write( "
