As of 2018, taxi cab tariffs for working hours in London, England, are as follows. • For the first 234.8 metres or 50.4 seconds (whichever is reached first) there is a minimum charge of 2.60 GBP. • For each additional 117.4 metres or 25.2 seconds (whichever is reached first), or part thereof, if the distance travelled is less than 9656.1 metres there is a charge of 0.20 GBP. • Once the distance has reached 9656.1 metres then there is a charge of 0.20 GBP for each additional 86.9 metres or 18.7 seconds (whichever is reached first), or part thereof. (a) Develop a piecewise linear model for the cost, C, of a taxi ride based on the distance travelled, m, in metres. (b) Find the cost of 0.2 km, 5 km, and 15 km rides. (c) Develop a piecewise linear model for the cost, D, of a taxi ride based on the time taken, t, in seconds, ignoring distance.

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Question
Transcribed Image Text:As of 2018, taxi cab tariffs for working hours in London, England, are as
follows.
• For the first 234.8 metres or 50.4 seconds (whichever is reached first)
there is a minimum charge of 2.60 GBP.
• For each additional 117.4 metres or 25.2 seconds (whichever is
reached first), or part thereof, if the distance travelled is less than
9656.1 metres there is a charge of 0.20 GBP.
Once the distance has reached 9656.1 metres then there is a charge of
0.20 GBP for each additional 86.9 metres or 18.7 seconds (whichever
is reached first), or part thereof.
(a) Develop a piecewise linear model for the cost, C, of a taxi ride based
on the distance travelled, m, in metres.
(b) Find the cost of 0.2 km, 5 km, and 15 km rides.
(c) Develop a piecewise linear model for the cost, D, of a taxi ride based
on the time taken, t, in seconds, ignoring distance.
(d) Find the cost of 0.5 minute, 5 minute, and 15 minute rides.
(e) Given that the actual taxi fare is always the greater of the two
models, find:
(i) the cost of a ride that takes 10 minutes to go 4 km
(ii) the cost of a ride that takes 5 minutes to go 4 km.
