Answer 2

Hello!

Answer:

`\Large \boxed{ \sf 93km}`

Explanation:

→ We want how many kilometres does he travel in 3 hours.

​

→ We know that the car travels 31 km in 1 hour.

So we have this table:

`\begin{tabular}{ l c r } Distance (km) & 31&x \\ Time (hours) & 1 &3 \\ \end{tabular}`

Let's use the method of the cross:

`\sf x = 3 * 31 / 1 = \boxed{ \sf 93}`

Conclusion:

The car will travel 93 km in 3 hours.
