Answer 1

Given:

The speed of Mario's kart is

$v=42\text{ miles/h}$

To find:

How far does he drive in 1.7 minutes?

Explanation:

The speed is,

$\begin{gathered} v=42\text{ miles/h} \\ =42\times1.6\text{ km/h} \end{gathered}$

The distance Mario drives is,

$\begin{gathered} d=vt \\ =42\times1.6\times\frac{1.7}{60}\text{ km} \\ =1.90\text{ km} \end{gathered}$

Hence, the required distance is 1.90 km.
