Answer:
t = 3.4 hour
Step-by-step explanation:
Distance to be covered by Shareen, d = 9.52 miles
The average speed of Shareen, v = 2.8 mph
We need to find the time taken by Shareen to complete the walk.
The formula for average speed,
v = distance/time
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{9.52}{2.8}\\\\t=3.4\ \text{hour}[/tex]
Hence, it will take 3.4 hour to complete the walk.
