Answer:
The third puzzle took 152 minutes.
Step-by-step explanation:
Given that,
Jeremy finished 3 puzzles in 266 minutes.
The second puzzle took twice as long as first.
The third puzzle took twice as long as the second one.
Assume that, the first puzzle took x minutes.
So, Second puzzle took= 2x minutes.
Third puzzle took =2(2x) minutes
=4x minutes
According to the problem,
x+2x+4x=266
⇒7x=266
[tex]\Rightarrow x=\frac{266}{7}[/tex]
⇒x=38 minutes
The third puzzle took = (4×38) minutes
=152 minutes
