Answer:
Step-by-step explanation:
A. Hours driving on monday= [tex]5\frac{3}{4}[/tex]=23/4 hours (5 x 4 +3)
Hours driving on tuesday= [tex]4\frac{3}{4}[/tex]=19/4 hours (4 x 4 +3)
Total hours = 23/4 + 19/4 = 42/4 = [tex]10\frac{2}{4}[/tex] hours
B. Total hours driving = Hours driving on (Monday + tuesday + wednesday + thursday)
Hours driving on wednesday= [tex]2\frac{1}{4}[/tex]=9/4 hours (2 x 4 +1)
Hours driving on thursday= [tex]6\frac{3}{4}[/tex]=27/4 hours (6 x 4 +3)
Total hours driving = 23/4 + 19/4 + 9/4 +27/4 = 78/4 = [tex]19\frac{2}{4}[/tex] hours
