Answer 2

Calculating the Distance Traveled by a Car

To calculate the distance traveled by a car at a speed of 75 km/h over different time intervals, we can use the formula:

Distance = Speed × Time

Let's calculate the distance for each time interval provided.

a) 3/4 hour (45 minutes)

Using the formula, the distance traveled in 3/4 hour can be calculated as:

Distance = 75 km/h × 3/4 hour

The distance traveled in 3/4 hour is 56.25 kilometers.

b) 40 minutes

To calculate the distance traveled in 40 minutes, we first need to convert 40 minutes to hours.

40 minutes = 40/60 hours = 2/3 hours

Using the formula, the distance traveled in 2/3 hour can be calculated as:

Distance = 75 km/h × 2/3 hour

The distance traveled in 40 minutes (2/3 hour) is 50 kilometers.

c) 50 minutes

Similar to the previous calculation, we need to convert 50 minutes to hours.

50 minutes = 50/60 hours = 5/6 hours

Using the formula, the distance traveled in 5/6 hour can be calculated as:

Distance = 75 km/h × 5/6 hour

The distance traveled in 50 minutes (5/6 hour) is 62.5 kilometers.

Conclusion

So, the car will travel: - 56.25 kilometers in 3/4 hour - 50 kilometers in 40 minutes - 62.5 kilometers in 50 minutes
