Respuesta :
it will be 80/2 and 0/10 you will have to multiply 10*80/2=4000
Answer:
It will take 2.5 hours.
Step-by-step explanation:
We know that,
[tex]Speed = \frac{Distance}{Time}[/tex]
If distance is 80 miles and time taken is 2 hours,
Then,
[tex]Speed = \frac{80}{2}=40\text{ miles per hour }[/tex]
Here sara is travelling with the constant speed which is 40 miles per hour,
If distance = 100 miles,
Hence, the time taken by her = [tex]\frac{Distance}{Speed}[/tex]
[tex]=\frac{100}{40}=2.5\text{ hours}[/tex]
