1. No, because the ratio 8:5 could be simplified from any factor of thirteen. 26 students in the class with 16 boys and 10 girls has the same ratio as 39 students in a class with 24 boys and 15 girls. So no, there is no accurate way to determine the number of students with the given information.
2. You can determine whether or not 2 ratios are equivalent if they can simplify to the same ratio. Using the first question as an example, 8:5 and 16:10 are the same ratio, because when you simplify the fraction 16/10, it is 8/5.

Car A travels 20 mph faster than Car B. In the same time that Car A travels 252 miles, Car B travels 196 miles. Find their speed

RoseWind [281]

<u>Answer:</u>

A = 70

B = 90

<u>Step-by-step explanation:</u>

We know that Car A travels 20 mph faster than Car B.

Assuming the speed of Car B to be x and the speed of Car A to be x+20, we can write:

$\frac{196}{x} =\frac{252}{x+20}$

Taking the reciprocal of both sides to make x the subject:

$196(x+20)=252x$

$196x+3920=252x$

$252x-196x=3920$

$56x=3920$

$x=70$ ---> speed of Car A

Finding the speed of Car B: $x+20 = 70+20=90$

Therefore, the speed of Car A = 70 and the speed of Car B = 90.
