16. Trasnsline bus lef Nairobi at 8.00 am and travelled to Nakuru at an average speed of \( 80 \mathrm{~km} / \mathrm{h} . \mathrm{A} \) car left Nakuru at 3.30 am and travelled to Nairobi at an average speed of \( 120 \mathrm{~km} / \mathrm{h} \). Given that the distance between Nairobi and Nakuru is 400 km , Calculate. (a) The time the car arrived in Nairobi. (b) The time the two vehicles met. (c) The distance from Nairobi to the meeting point, 3 mks\( ) \) (d) The distance of the bus from Nakuru when the car arrived in.

QUESTION TWO Express each of the following as a single, simplified fraction. 2.1. \( \frac{4}{9}-\frac{2}{3}+\frac{7}{12} \) 2.2. \( \frac{-8}{13} \times \frac{5}{24} \div-\frac{25}{13} \) 2.3. \( \left(\frac{3}{7}+\frac{1}{4}\right) \times\left(2-\frac{69}{38}\right) \)

\( 37 ; 33 ; 29 ; x ; 21 ; \ldots \). Write down the value of \( x \). Determine the \( n^{\text {th }} \) term of the number pattern. Determine the \( 15^{\text {th }} \) term of the sequence. Which term is the first to have a negative value.

c) \( 8+(-18): 3= \)
