Harpreet covered a certain distance at 5 km/h in 4 hours 12 minutes. Find the time required
to cover the same distance at the speed of 7 km/h.

To solve this problem, we can break it down into two steps:

### Step 1: Calculate the distance covered by Harpreet
Given:
- Speed = 5 km/h
- Time = 4 hours 12 minutes

First, convert 4 hours 12 minutes into hours:
\[
\text{4 hours 12 minutes} = 4 + \frac{12}{60} = 4.2 \text{ hours}
\]

Now, use the formula:
\[
\text{Distance} = \text{Speed} \times \text{Time}
\]
\[
\text{Distance} = 5 \text{ km/h} \times 4.2 \text{ hours} = 21 \text{ km}
\]

### Step 2: Find the time required to cover the same distance at 7 km/h
Given:
- Speed = 7 km/h
- Distance = 21 km

Use the formula:
\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}}
\]
\[
\text{Time} = \frac{21 \text{ km}}{7 \text{ km/h}} = 3 \text{ hours}
\]

So, the time required to cover the same distance at 7 km/h is **3 hours**.

Would you like any further details or explanations? Here are five related questions:

1. How would the time change if Harpreet's speed were 10 km/h?
2. What is the formula for speed if you know the distance and time?
3. How would you convert 4 hours 12 minutes into minutes only?
4. What would be the distance covered if Harpreet traveled for 5 hours at 7 km/h?
5. How does speed affect the time taken to cover a fixed distance?

**Tip:** Always ensure that time units are consistent when performing calculations involving speed and time.
