Answer:
The charge for shovelling snow for 6 hour is 72 hours
Step-by-step explanation:
Given as :
The charge for shovelling snow for 2 [tex]\frac{1}{2}[/tex] hours is $30
Let The charge for shovelling snow for 6 hours = $ x
Now, Applying unitary method
∵ The charge for shovelling snow for 2 [tex]\frac{1}{2}[/tex] hours = $30
or, The charge for shovelling snow for [tex]\frac{5}{2}[/tex] hour = $30
So, The charge for shovelling snow for 1 hour = [tex]\frac{30×2}{5}[/tex] hour
∴ The charge for shovelling snow for 6 hour = [tex]\frac{30×2}{5}[/tex] × 6 hours
I.e The charge for shovelling snow for 6 hour = [tex]\frac{360}{5}[/tex] hours
= 72 hours
Hence The charge for shovelling snow for 6 hour is 72 hours Answer
