Answer:
x = 13
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
78(11x - 13) = 10140 ( divide both sides by 78 )
11x - 13 = 130 ( add 13 to both sides )
11x = 143 ( divide both sides by 11 )
x = 13
7 x 24 = 168 hours a week
168 x 60 = 10,080 minutes a week
10,080 x 60 = 604,800 seconds in a week
47/60 because there are 60 seconds in one minute
