Let’s solve each problem step by step.

Part 1: Fill in the blanks with “Speed”, “velocity”, or “acceleration”

We need to pick the right word based on what each sentence describes.

1. *A car moves 30 km/h to the east.*
→ This tells us how fast AND which direction. That’s velocity. (Speed is just how fast, no direction.)

2. *An object moves 100 km in 1 hour.*
→ This is total distance over time — that’s speed. No direction mentioned.

3. *A boy kicks the ball and after some time it slows down.*
→ Slowing down means its speed is changing — that’s acceleration. (Acceleration includes slowing down too!)

✔ So answers are:
1. velocity
2. speed
3. acceleration

Part 2: Choose the correct answer using Distance = Speed × Time

We’re given three triangle diagrams showing how to rearrange the formula:

- Distance = Speed × Time
- Time = Distance ÷ Speed
- Speed = Distance ÷ Time

Now let’s solve the questions.

Question 1:
*The speed of a car is 500 km/h. How much distance will it travel in 3 hours?*

Use: Distance = Speed × Time

= 500 km/h × 3 h
= 1500 km

Look at the options:
a. 1500 m → too small (meters, not kilometers)
b. 1500 m/h → wrong unit
c. 1500 km → ✔ Correct!
d. 1500 km/h → that’s speed, not distance

✔ Answer: c. 1500 km

Question 2:
*A car travels 300 km in 3 hours. What is its speed?*

Use: Speed = Distance ÷ Time

= 300 km ÷ 3 h
= 100 km/h

Options:
a. 900 km/h → too big
b. 100 km/h → ✔ Correct!
c. 900 m/s → way too fast and wrong units
d. 100 m/s → also wrong units (that’s like 360 km/h!)

✔ Answer: b. 100 km/h

Final Answer:
Part 1:
1. velocity
2. speed
3. acceleration

Part 2:
1. c. 1500 km
2. b. 100 km/h
