Interconcept | Term 2 Chapter 5

Able to Create problems integrating time, money and distance

Thinking about travel, costs, and duration helps us understand how these concepts work together. Consider the following scenarios:

(i) Raju travelled 20 km in 1 hour Dinu travelled 5 km in Half an hour who travelled fast? Which vehicle he used?

(ii) In metro train ₹ 60 charged for Half an hour. Deepa has ₹ 200. How many hours does she travel in metro train?

(iii) Senthil spent ₹ 80 for 50 km. Gowtham spent ₹ 50 for 30 km. Who travelled at lowcost?

From these above questions, we can conclude the relationship between Time, Distance and Money. These are interrelated.

$$ \text{Speed} = \frac{\text{Time}}{\text{Distance}} $$

$$ \text{Time} = \frac{\text{Distance}}{\text{Speed}} $$

$$ \text{Distance} = \text{Speed} \times \text{Time} $$

Example

If Sabari Walked 5 Hours at a speed of 5Km/Hour, then how much did he covered?

Distance = Speed × Time
= 5 × 5
Distance covered by Sabari = 25 Km
