a motorboat can maintain a constant speed of 15 miles per hour relative to the water. the boat makes a trip upstream to a certain point in 38 minutes; the return trip takes 22 minutes. What is the speed of the current?

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
