How much more time did Maria spend doing research than checking email ?
tensa zangetsu [6.8K]

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 = \frac{30}{100} *24= 7.2

Time spent on checking email = 15% of 24 = \frac{15}{100} *24= 3.6

so, 7.2 - 3.6 = 3.6

Hence , Maria spends 3.6 hours more on doing research than checking email.
