Answer:

It will take 2.5 hours.

Step-by-step explanation:

We know that,

Speed = \frac{Distance}{Time}

If distance is 80 miles and time taken is 2 hours,

Then,

Speed = \frac{80}{2}=40\text{ miles per hour }

Here sara is travelling with the constant speed which is 40 miles per hour,

If distance = 100 miles,

Hence, the time taken by her = \frac{Distance}{Speed}

=\frac{100}{40}=2.5\text{ hours}
