Answer:
B. 4.8 miles per hour
Step-by-step explanation:
We are given that,
Distance needed to walk by Danielle = 4 miles
Time needed to reach the destination = 50 minutes = 0.83 miles
It is required to find the speed needed by Danielle.
Since, we know,
[tex]Speed=\frac{Distance}{Time}[/tex]
i.e. [tex]Speed=\frac{4}{0.83}[/tex]
i.e. Speed = 4.8 miles per hour
Hence, she needs to walk 4.8 miles per hour to reach her destination.
