Stewart cycles at an average speed of 10 kilometres per hour. How many days will it take him to travel 1000 kilometres, if he cannot cycle more than 8 hours per day?

For this problem, we have to divide 1000 km by the product of hours per day and average speed:

\(days=\frac{1000}{10*8=80}\)

\(days=\frac{960+40}{80}\)

\(days=\frac{960}{80}+\frac{40}{80}\)

\(days=12+\frac{1}{2}\)

\(days = 12.5\)

Stewart will take 12.5 days to travel 1000km.

**Stewart cycles at an average speed of 10 kilometres per hour. **

**How many days will it take him to travel 1000 kilometres,**

**if he cannot cycle more than 8 hours per day?**

**\(\begin{array}{|rcll|} \hline && 1000\ km \cdot \frac{1\ \text{hour}}{10\ km}\cdot \frac{1\ \text{day}}{8\ \text{hour}} \\ &=& \frac{1000}{10\cdot8} \ \text{days} \\ &=& \frac{100}{8} \ \text{days} \\ &=& \frac{25}{2} \ \text{days} \\ &=& 12.5 \ \text{days} \\ \hline \end{array}\)**

It will take him to travel 1000 kilometers about **12.5 days**
