Answer 1

we have to calculate how  much time they spend in a day.

Jake:

3/4 hour-----------------------2 days
x---------------------------------1 day

x=(3/4 hour*1day) / 2 days=3/8 hours

Kyile:
1/4 hour------------------------6 days.
x----------------------------------1 day

x=(1/4 hour * 1 days) / 6 days=1/24 hours

3/8 hours>1/24 hours, therefore
Jake sepent more time total working on his project.
