Samacheer Kalvi Class 5 Maths Solutions Term 2 Chapter 5 Interconcept Exercise 5.2

Question 1. Answer the following

🎯 Exam Tip: Remember the formula: Time = Distance / Speed. Always check that the units for distance and speed match (e.g., Km and Km/hour) to avoid errors.

Question 2. Wilson reached 240 Km at the speed of 60 Km/hour. How muc time did he travelled?
Answer:
Distance travelled \( = 240 \) Km
Speed \( = 60 \) Km/hour
Time taken \( = \frac { \text{Distance} }{ \text{Speed} } \)
\( = \frac { 240 }{ 60 } \)
\( = 4 \) hours
Wilson travelled for 4 hours. Calculating time helps us understand how long a trip will be.
In simple words: Wilson went 240 Km at 60 Km/hour. To find the time he took, divide the distance (240) by his speed (60). This gives 4 hours.

🎯 Exam Tip: When solving word problems, write down the given values (distance, speed) first. This helps in correctly applying the formula.

Question 3. Anbarasan travelled 350 Km at the speed of 70 Km/hour. Find the time taken for his travel.
Answer:
Distance travelled \( = 350 \) Km
Speed \( = 70 \) Km/hour
Time taken \( = \frac { \text{Distance} }{ \text{Speed} } \)
\( = \frac { 350 }{ 70 } \)
\( = 5 \) hours
Anbarasan took 5 hours for his travel. This calculation is a basic concept in understanding motion.
In simple words: Anbarasan traveled 350 Km at a speed of 70 Km/hour. To find the time, divide 350 by 70, which equals 5 hours.

🎯 Exam Tip: Double-check your division, especially with larger numbers, to make sure you get the correct time in hours.

Question 4. Nazar travelled 360 Km at the speed of 90 Km/hour. Find the time taken for his travel.
Answer:
Distance travelled \( = 360 \) Km
Speed \( = 90 \) Km/hour
Time taken \( = \frac { \text{Distance} }{ \text{Speed} } \)
\( = \frac { 360 }{ 90 } \)
\( = 4 \) hours
Nazar's travel took 4 hours. Understanding this relationship between distance, speed, and time is very useful.
In simple words: Nazar drove 360 Km at 90 Km/hour. Divide 360 by 90 to find the travel time, which is 4 hours.

🎯 Exam Tip: Make sure to clearly write out the formula for time, distance, and speed before plugging in the numbers. This helps in showing your working steps.

Question 5. Fathima reached 480 Km at the speed of 120 Km/hour. How much time did she travelled?
Answer:
Distance travelled \( = 480 \) Km
Speed \( = 120 \) Km/hour
Time taken \( = \frac { \text{Distance} }{ \text{Speed} } \)
\( = \frac { 480 }{ 120 } \)
\( = 4 \) hours
Fathima traveled for 4 hours. These calculations help in everyday situations, like planning road trips.
In simple words: Fathima covered 480 Km at 120 Km/hour. Divide 480 by 120 to get the travel time, which is 4 hours.

🎯 Exam Tip: When dividing, you can often simplify the numbers first (e.g., cancel out zeros) to make the calculation easier.
