Solution:
we have been asked to find
How much more time did Maria spend doing research ?
Maria spends doing research = 30%
and using email = 15% of a day (24 hours)
Time spent on research = 30% of 24 = [tex] \frac{30}{100} *24= 7.2 [/tex]
Time spent on checking email = 15% of 24 = [tex] \frac{15}{100} *24= 3.6 [/tex]
so, [tex] 7.2 - 3.6 = 3.6 [/tex]
Hence , Maria spends 3.6 hours more on doing research than checking email.
