Answer 1

Машина преодолеет путь в 49,5 км

Answer 2

Problem Statement

The problem states that a car traveled a distance of 11 km in 10 minutes. The task is to find out how much distance the car will cover in 45 minutes while moving at the same speed and express the car's speed in kilometers per hour.

Solution

To find the distance the car will cover in 45 minutes, we can use the formula: distance = speed × time

First, let's convert the given time of 10 minutes to hours: 10 minutes = 10/60 hours = 1/6 hours

Now, we can calculate the speed of the car using the given distance and time: Speed = distance / time

Substitute the given values: Speed = 11 km / (1/6 hours) Speed = 11 km * 6 = 66 km/h

Now, we can find the distance the car will cover in 45 minutes: Distance = speed × time Distance = 66 km/h × (45/60) h Distance = 66 km/h × 0.75 Distance = 49.5 km

So, the car will cover a distance of 49.5 km in 45 minutes while moving at the same speed.

Conclusion

The speed of the car is 66 km/h and it will cover a distance of 49.5 km in 45 minutes while moving at the same speed.
