Let x be the speed of the first car in miles per hour. After 12 hours it will have gone 12x miles. The other car, driving east, has speed x+ 4. After 12 hours it will have gone 12(x+ 4) miles. Again by the Pythagorean theorem,

(12x)^2+(12(x+4)^2=600^2. Solve that equation for x.

Answer:

The required value for the blank is 21.8696

Step-by-step explanation:

Consider the provided information,

4,275.50= 391/2 of ____

Replace blank with x.

4,275.50 = 391/2 of x

Use sign of multiplication for "of".

$4,275.50 = \frac{391}{2} \times x$

Solve the above expression for x.

$x=\frac{4,275.50\times 2}{391}$

$x=21.8696$

Thus, the required value for the blank is 21.8696
