Tammy drove 715 miles in 11 hours at the same rate how many miles would she drive in 5 hours

For this case we can propose a rule of three:

715 miles ------------> 11 hours

x ---------------------------> 5 hours

Where:

x: Represents the number of miles driven in 5 hours. So, we have:

Finally we have Tammy drove 325 miles in 5 hours.

325 miles

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

10000
