<PRE><B>Question 1003136</B>
Two cyclists are travelling side by side along a long straight
cycle track, 

one at 30 km/h and 
the other at 31 km/h.
ll need
to gain 8 m relative to the slower cyclist 


a) the time taken for the faster cyclist to overtake the slower
cyclist

difference between cyclists speed = 1km/h = 0.28m/s

distance = 8 m

time = d/r

8/0.28

= 28.7 seconds

b) the distance travelled by the faster cyclist in this time

31 km/h =8.6m/s

Distance travelled = 8.6 * 28.7 =246.82 m OR 0.246 km</PRE>
