2 cars started to move from C and from D, towards one another. The car that starts at point C moves twice as fast as the car that starts at point D. How far from boston will those two cars meet?

They meet at 92 miles from C or 46 miles from D.

Step-by-step explanation:An object is said to have constant speed if it travels the same distance at the same time. The ratio between the distance x and the time t is the speed and is given by

Solving for x

The car starting from C has double speed as the car starting from D. this means

When both cars meet, they travel these distances

The sum of both distances is x = 256 - 118 = 138 miles.

Or, equivalently

Using the relations of the speeds:

Solving for t

The distance traveled by the car from c is

The distance traveled by the car from d is

There is no reference of where Boston is located, thus we can only refer the distances respect to C or D, as shown above

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
