A bus left Mombasa and traveled towards Nairobi at an average speed of 60km/hr. after 21/2 hours; a car left Mombasa and traveled along the same road at an average speed of 100km/ hr. If the distance between Mombasa and Nairobi is 500km, Determine
(a) (i) The distance of the bus from Nairobi when the car took off (ii) The distance the car traveled to catch up with the bus (b) Immediately the car caught up with the bus, the car stopped for 25 minutes. Find the new average speed at which the car traveled in order to reach Nairobi at the same time as the bus. Form 2 Mathematics
The diagram below ( not drawn to scale) represents the cross- section of a solid prism of height 8.0 cm
(a) Calculate the volume of the prism
(b) Given that the density of the prism is 5.75g/cm3, calculate its mass in grams (c) A second prism is similar to first one but is made of a different materials. The volume of the second is 246.24cm3 (i) calculate the area of the cross section of the second prism (ii) Given that the ratio of the mass of the first to that of the second is 2: 5 and the density of the second prism Form 2 Mathematics
On the Cartesian plane below, triangle PQR has vertices P(2, 3), Q ( 1,2) and R ( 4,1) while triangles P" Q" R" has vertices P" (-2, 3), Q" ( -1,2) and R" ( -4, 1)
(a) Describe fully a single transformation which maps triangle PQR onto triangle P"Q"R"
(b) On the same plane, draw triangle P"Q"R", the image of triangle PQR, under reflection in line y = -x (c) Describe fully a single transformation which maps triangle P"Q"R" onto triangle P"Q"R (d) Draw triangle P"Q"R" such that it can be mapped onto triangle PQR by a positive quarter turn about ( 0,0) (e) State all pairs of triangle that are oppositely congruent Form 1 Mathematics
In the year 2001, the price of a sofa set in a shop was Kshs 12,000
(a) Calculate the amount of money received from the sales of 240 sofa sets that year (b) (i) In the year 2002 the price of each sofa set increased by 25% while the number of sets sold decreased by 10% Calculate the percentage increase in the amount received from the sales (ii) If at the end of year 2002, the price of each sofa set changed in the ration 16:15, calculate the price of each sofa set in the year 2003 (c) The number of sofa sets sold in the year 2003 was P% less than the number sold in the year 200. Calculate the value of P, given that the amounts received from sales if the two years were equal.
