Answer 1

To find Sharon's average speed, we can use the formula for speed, which is:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

In Sharon's case:

• Distance = 140 miles
• Time = 4 hours

Plugging in the values:

\[ \text{Speed} = \frac{140 \text{ miles}}{4 \text{ hours}} = 35 \text{ mph} \]

So, Sharon's average speed for the trip was 35 mph.
