Rohit takes `4 4/5` minutes to make a complete round of a circular park. How much time will 5 he take to make 15 rounds

Answer

To solve the problem step by step, we will first convert the mixed number into an improper fraction, then calculate the time taken for 15 rounds.

### Step 1: Convert the mixed number to an improper fraction
Rohit takes `4 4/5` minutes for one round. We can convert this mixed number into an improper fraction.

- The whole number part is 4.
- The fractional part is `4/5`.

To convert it:
\[ 4 \frac{4}{5} = \frac{(4 \times 5) + 4}{5} = \frac{20 + 4}{5} = \frac{24}{5} \text{ minutes} \]

### Step 2: Calculate the time for 15 rounds
Now that we know the time for one round is `\(\frac{24}{5}\)` minutes, we can find the time for 15 rounds by multiplying the time for one round by 15.

\[ \text{Time for 15 rounds} = 15 \times \frac{24}{5} \]

### Step 3: Perform the multiplication
To multiply, we can simplify:
\[ 15 \times \frac{24}{5} = \frac{15 \times 24}{5} = \frac{360}{5} \]

Now, divide 360 by 5:
\[ \frac{360}{5} = 72 \text{ minutes} \]

### Conclusion
Therefore, Rohit will take **72 minutes** to complete 15 rounds of the circular park.
