TMA 01

Question 1

Cut-off date 12 March 2019

–

10 marks

This question is based on your work on MU123 up to and including Unit 1,

concentrating on good mathematical communication (GMC).

Consider the following TMA question:

The Shard in London is the tallest building in the United

Kingdom. It is 306 m tall, which is the equivalent of 70 London

buses stacked one on top of another. Find the height of one

London bus, in metres, giving your answer to one decimal place.

Here is a student’s attempt at a solution, with the correct numerical result:

306 = 306/70 = 4.4 = height

(a) With reference to good mathematical communication (GMC), describe

three aspects of the student’s solution that could be improved.

[6]

(b) Write out your own solution to this question.

[4]

You will find pages 54–8 of Book A useful.

Question 2

30 marks

This question is based on your work on MU123 up to and including Unit 1.

(a) A recipe for macaroni cheese for 4 people uses 250 g of macaroni.

Calculate the quantity of macaroni needed for 10 people.

[5]

(b) A swimming club has 65 members, and 18 of these are aged over 50.

Calculate the percentage of swimming club members who are aged

over 50. Give your answer correct to the nearest whole number.

[5]

(c) There are 350 children enrolled in a school. On the first Monday in

March, 96% of the children were present.

(i)

Calculate the number of children who were present on this day.

(ii) Write the number of children who were present as a fraction of the

total number of children in the school. Give your answer in its

simplest form.

(d) (i)

A town has a population of 15 500. The population is forecast to

rise by 3% over the next year. Calculate the new population after

the 3% rise, giving your answer correct to three significant figures.

(ii) The following year, the population is forecast to rise by 1%.

Calculate the new population after this 1% rise, giving your answer

correct to three significant figures.

(e) An amateur meteorologist working in central England found that the

local rainfall was 102.4 mm in November 2016 and 76.9 mm in

November 2017. Calculate the percentage decrease in rainfall between

November 2016 and November 2017, giving your answer correct to one

decimal place.

This question is based on your work on MU123 up to and including Unit 2.

(a) Alex is planning to walk the Cleveland Way in Yorkshire during the

summer. On the first day he will walk from Helmsley to Sutton Bank.

The distance is 16 km, and Alex estimates that this stage of the walk will

take 3 hours 45 minutes. Find his average speed in km per hour for this

stage of the walk, giving your answer correct to two significant figures.

[5]

(b) The next stage of the walk, from Sutton Bank to Osmotherley, is

19.2 km. If Alex walks at the same average speed, find how long this

stage of the walk will take. Give your answer in hours and minutes.

[5]

1 : 25 000 is 70.9 cm. Find the corresponding distance on the ground

(in km), giving your answer correct to three significant figures.

[5]

(d) The distance of the section of the walk from Clay Bank to Kildale is

15.1 km, and the height ascended is 220 m. Use Naismith’s Rule

T =

D

H

+

,

where T is the time for the walk in hours, D is the horizontal distance

walked in km, and H is the height climbed in metres, to estimate the

time taken for this section of the walk. Give your answer correct to the
