Question

Mathew drives $60$ miles in $2$ hours. How much distance will he cover in $5$ hours if he drives with the same speed?

• A. $120$ miles
• B. $150$ miles
• C. $100$ miles
• D. $300$ miles

Answer 1

The correct option is B $150$ miles

Draw a double number line to calculate the distance.

Mathew covers $60$ miles in $2$ hours.

The ratio is $\frac{60}{2}=\frac{30}{1},$

Which is same as $30:1$.

Add $30$ to the top line and $1$ to the bottom line.


Similarly, add the numbers. Subsequently, the number line will look like this.

From the above double number line, we can conclude that in $5$ hours, Mathew covered a distance of $150$ miles.
