Question

In one day, Annie traveled 7 times the sum of the number of hours Brian traveled and 4. Together they traveled 56 hours. Find the number of hours each person traveled.

Answer 1

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.
