(b) The average speed of a bus is 64 km/h.

Calculate:

(i) the distance travelled (in km) by the bus if its departure time is 0820 hour and

the arrival time is 1100 hour.

(ii) the arrival time of the bus if its departure time is 0900 hour and the distance

travelled is 160 km.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
