Find out the hours travels by the annie and brian
To proof - Let us assume that the hours travelled by brian be x.
As given in the question Annie traveled 7 times the sum of the number of hours Brian traveled and 4.
So, Annie travelled = 7(x+4) and Brian travelled = x
Total hours travel by them is 56.
According to question:
x +7 ( x+4) = 56
x+7x +28=56
8x=56-28
x=3.5 hours
Therefore, Brian travel for 3.5 hours and Annie travels for the 52.5 hours.
