Question

#1: In Picture!

#2: Explain Aaron's mistake using 1-3 complete sentences.

Please answer both :)

Answer 1

1. 1.45 in/h
2. see below

Explanation:

1. The appropriate "dimensional analysis" is ...

`(2.9\,ft)/(1\,day)\cdot(12\,in)/(1\,ft)\cdot(1\,day)/(24\,h)=(2.9\cdot 12\cdot 1\,day\cdot ft\cdot in)/(1\cdot 1\cdot 24\,day\cdot ft\cdot h)=1.45(in)/(h)`

2. Aaron used the inverse of the correct days to hours conversion factor. The units he ends up with are in·h/day², not in/h. And the calculation he did does not match the expression he wrote.
