3/4 of an hour is 45 minutes. His brother takes 1/3 of the time, 1/3 of 45 min is 15 min. 5*15=75 min or 1 + 15/60 = 1.25 hours

Ronch [10]

 

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(4/3) = -1......( perpendicular to a line with a slope of   4/3)            because :     4x-3y =8...y=(4/3)x-8/3    )     </span>

<span>
a = -3/4         y=(-3/4)x+b
the line that passes through (3, -2) :- 2 = (-3/4)(3)+b
b =1/4
<span> the equation is :  y  = (-3/4)x+1/4</span></span>
