Question

A car travels 600 km on a journey and covers this distance in 6 hours and 15 minutes. Calculate the average speed per hour.

UpStudy AI · Accepted Answer

To calculate the **average speed** of the car, you can use the formula:

$$
\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}
$$

**Given:**
- **Total Distance** = 600 kilometers
- **Total Time** = 6 hours and 15 minutes

**Step 1: Convert Time to Hours**

First, convert the total time into hours. Since there are 60 minutes in an hour:

$$
15 \text{ minutes} = \frac{15}{60} \text{ hours} = 0.25 \text{ hours}
$$

So,

$$
\text{Total Time} = 6 \text{ hours} + 0.25 \text{ hours} = 6.25 \text{ hours}
$$

**Step 2: Calculate Average Speed**

Now, plug the values into the average speed formula:

$$
\text{Average Speed} = \frac{600 \text{ km}}{6.25 \text{ hours}} = 96 \text{ km/h}
$$

**Answer:**
The car's average speed is **96 kilometers per hour**.
The car's average speed is 96 kilometers per hour.
