Let's solve each problem step by step using the formula:
$$
\text{Distance} = \text{Speed} \times \text{Time}
$$
We'll make sure all units are consistent (especially converting minutes to hours when needed, since speed is in km/h).
---
1. Car:
- Speed = 130 km/h
- Time = 3 hours
$$
\text{Distance} = 130 \times 3 = 390 \text{ km}
$$
✔ Answer: 390 km
---
2. Plane:
- Speed = 500 km/h
- Time = 5 hours
$$
\text{Distance} = 500 \times 5 = 2500 \text{ km}
$$
✔ Answer: 2500 km
---
3. Bicycle:
- Speed = 20 km/h
- Time = 90 minutes = $ \frac{90}{60} = 1.5 $ hours
$$
\text{Distance} = 20 \times 1.5 = 30 \text{ km}
$$
✔ Answer: 30 km
---
4. Helicopter:
- Speed = 240 km/h
- Time = 20 minutes = $ \frac{20}{60} = \frac{1}{3} $ hours ≈ 0.333 hours
$$
\text{Distance} = 240 \times \frac{1}{3} = 80 \text{ km}
$$
✔ Answer: 80 km
---
5. Walking:
- Speed = 6 km/h
- Time = 150 minutes = $ \frac{150}{60} = 2.5 $ hours
$$
\text{Distance} = 6 \times 2.5 = 15 \text{ km}
$$
✔ Answer: 15 km
---
6. Motorbike:
- Speed = 60 km/h
- Time = 12 minutes = $ \frac{12}{60} = 0.2 $ hours
$$
\text{Distance} = 60 \times 0.2 = 12 \text{ km}
$$
✔ Answer: 12 km
---
7. Scooter:
- Speed = 80 km/h
- Time = 30 minutes = $ \frac{30}{60} = 0.5 $ hours
$$
\text{Distance} = 80 \times 0.5 = 40 \text{ km}
$$
✔ Answer: 40 km
---
✔ Final Answers:
1. Car:
390 km
2. Plane:
2500 km
3. Bicycle:
30 km
4. Helicopter:
80 km
5. Walking:
15 km
6. Motorbike:
12 km
7. Scooter:
40 km
