Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides
168x - 280 = 160x - 160 ( subtract 160x from both sides )
8x - 280 = - 160 ( add 280 to both sides )
8x = 120 ( divide both sides by 8 )
x = 15
First we need to find the rate which is the total amount driven divided by the total time.
152/4 = 38 miles per hour.
No we take the total driven miles given and divide it by the rate to find how long it would take!
760/38 = 20 hours!
Hope this helps :D
