To find the answers to your questions, we'll start with the information given:
- Distance: 300 meters
- Time: 6 minutes
1. Driving Time for 15,000 Meters
First, we need to determine the speed of the toy car to figure out how long it takes to drive 15,000 meters.
Speed Calculation:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{300 \text{ meters}}{6 \text{ minutes}} = 50 \text{ meters per minute} \]
Now, we need to find out how long it will take to drive 15,000 meters at this speed.
Time Calculation:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{15,000 \text{ meters}}{50 \text{ meters/minute}} = 300 \text{ minutes} \]
Now, we convert minutes into hours:
\[ 300 \text{ minutes} = \frac{300}{60} \text{ hours} = 5 \text{ hours} \]
So, it will take the toy car 5 hours to drive 15,000 meters.
2. Speed of the Toy Car in Kilometers per Hour
We already calculated the speed to be 50 meters per minute. Now, let's convert this speed into kilometers per hour.
First, we convert meters into kilometers:
\[ 50 \text{ meters/minute} = 50 \div 1000 \text{ kilometers/minute} = 0.05 \text{ kilometers/minute} \]
Now we convert minutes to hours:
\[ 0.05 \text{ kilometers/minute} \times 60 \text{ minutes/hour} = 3 \text{ kilometers/hour} \]
Thus, the speed of the toy car is 3 kilometers per hour.
Summary of Answers:
- Time to drive 15,000 meters: 5 hours
- Speed of the toy car: 3 kilometers per hour
