Answer:
60 km/hr
Step-by-step explanation:
100+100
_______ =3x
8
3x= 200/8
x=200/24 mps
=30mph
final speed is 60km/hr because its 2x's more =2*30=60
In algebra, the conversion of a more complex number to a simpler mixed number is rather simple. For the repeated numbers, which are designated by the bar above them, we simply have to put over 9 for each number repeated and 0 for the non-repeated numbers.
In this item, we have 1.28 with bar above 28 signifying that the number can also be written as 1.28282828.... The mixed number is then equal to,
<em>1 and 28/99 or 1 and 28 over 99</em>
Therefore, the answer to this item is the second choice.
