Answer:
She need to walk 5 miles/hr.
Step-by-step explanation:
Consider the provided information.
Danielle needs to walk 2.5 miles. If she wants to reach her destination in 30 minutes (1/2 hour), we need to find the speed of Danielle.
[tex]Speed=\frac{Distance}{Time}[/tex]
The distance is given 2.5 miles and time is 1/2 hours.
1/2 hours = 0.5 hours
Substitute the respective values in the above formula.
[tex]Speed=\frac{2.5}{0.5}[/tex]
[tex]Speed=\frac{25}{5}[/tex]
[tex]Speed=5[/tex]
Hence, she need to walk 5 miles/hr.
