Answer:
25.05 miles per week
Step-by-step explanation:
We know that,
1 mile = 1760 yards
⇒ 920 yards = 0.522 mile
1 week = 168 hour
We need to find ts speed in miles per week.
Speed = distance/time
[tex]v=\dfrac{920\ \text{yards}}\\\\v=\dfrac{0.522\ \text{miles}}{\dfrac{3.5}{168}\ \text{week}}\\\\v=25.05\ \text{miles/week}[/tex]
So, the speed of the object is 25.05 miles per week.
