Question

Ana bikes for 5.5 hours. She covers a distance of 57.75 mi.



Assuming she bikes at a constant speed, how fast was Ana biking?



5.5 mi/h

7.5 mi/h

9.5 mi/h

10.5 mi/h

Answer 1

Answer:

$10.5\:mi/h$

Step-by-step explanation:

It was given that Ana bikes for 5.5 hours.

$\Rightarrow t=5.5$

She covers a distance of $57.75\:mi$

$\Rightarrow d=57.75$

We calculate the speed as follows

$Speed=\frac{Distance}{Time\:taken}$

$\Rightarrow Speed=\frac{57.75}{5.5}$

$\Rightarrow Speed=10.5\:mi/h$

The correct answer is D

Answer 2

Answer:

10.5 mi/h

Step-by-step explanation:

I took the test online in K12 and when I reviewed it said that 10.5 is the correct answer.
