Question

An object is moving at a speed of 920 yards every 3.5 hours Express the speed in miles per week

Answer 1

25.05 miles per week

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

`v=\frac{920\ \text{yards}}\\\\v=\frac{0.522\ \text{miles}}{(3.5)/(168)\ \text{week}}\\\\v=25.05\ \text{miles/week}`

So, the speed of the object is 25.05 miles per week.
