Answer: He read 40% of the total time.
Step-by-step explanation:
As per given,
Total time he spent = 2 +1+2 = 5 hours
Number of hours he spent on reading = 2 hours
The percent of the total time he read = [tex]\dfrac{\text{Number of hours read}}{\text{Total time spent}}\times100[/tex]
[tex]=\dfrac{2}{5}\times100\\\\=40\%[/tex]
i.e. The percent of the total time he read = 40%
Hence, he read 40% of the total time.
