Answer 2

34 miles is the distance from point A will they meet.

Explanation:

Proportion states that the two ratios or fractions are equal.

Given the statement:

Distance between point A and B (i.e AB) = 200 mi.

Let the cyclist speed be c, and motor- speed be m;

then;

c = 17 mph and m=83 mph

Let they meet at distance x miles from a point A.

By definition of proportion, we have;

`(x)/(17) =(200-x)/(83)`

By cross multiply;

`83x = 17(200-x)`

Using distributive property,
`a\cdot(b+c) =a\cdot b+ a\cdot c`

`83x = 3400 - 17x`

Add 17x both sides we get;

`83x+ 17x= 3400 - 17x +17x`

Simplify:

100x = 3400

Divide by 100 on both sides we get;

x = 34 miles

Therefore, the distance from point A will they meet is, 34 miles.
