11. A speed boat sets off from an island M on a bearing of 0800 to an island X at an average speed of 150kmh-1, island X is 450 km from island M. at X it alters its course to a bearing of 2000 and maintains the average speed of 150kmh-1 for 3 hours until it reaches island Y. it then moves to island P is 400 km from island M.

a) Using a scale of 1 cm to represent 50 km, construct a scale drawing to show the route of the speed boat.

b) Use the scale drawing in (a) to find the distance PY.

c) Calculate the

(i) Total time taken for the speed boat to move from M to P.

(ii) Speed boat's average speed for the whole journey.

12. The Venn diagram below shows the members of a district council who sit on three different committees of works (W), production (P) and Finance (F).


a) Determine the value of x, y and z.

b) Find the total number of members who

b) A mini bus travels from migyera to Kampala, a distance of 156km, at a certain average speed of Vkm/hr. on the return journey, it increases the average speed by 4 km/hr and takes 15minutes less. Find the average speed V from Migyera to Kampala.

14. The table below shows time (t) in seconds and velocity (V) in m/s of an object.

t(s) 0 1 2 3 4 5 6

b) Use your graph in (a), to find the

(i) Times at which the speed of the object is 0.8 m/s.

(ii) Acceleration of the object when the time is 2 seconds.

c) If the total distance covered by the object was 7.5m, what was its average speed?
