Question

An object is moving at a speed of 9 kilometers every 6.5 years. Express this speed in inches per day. Round your answer to the nearest whole number.

Answer 1

The object is moving at 149 inches per day.

Explanation:

The speed can be converted from km/y to in/d taking into account that:

In 1 kilometer we have 39370.1 inches and in 1 year we have 365 days, hence:

`V = (9 km)/(6.5 y)*(39370.1 in)/(1 km)*(1 y)/(365 d) = 149 in/d`

Therefore, the object is moving at 149 inches per day.

I hope it helps you!
