Question

A robin flew rrr meters per second, and a cardinal flew ccc meters per second. The birds flew for ttt seconds. The expression t(r-c)t(r−c)t, left parenthesis, r, minus, c, right parenthesis describes how many more meters the robin flew than the cardinal flew during that time. What does (r-c)(r−c)left parenthesis, r, minus, c, right parenthesis represent in this context?

Answer 2

Answer:

$(r-c)$ represents Relative Speed of Robin with respect to Cardinal.

Step-by-step explanation:

Given:

Speed of Robin = 'r' m/s

Speed of cardinal = 'c' m/s

Time flew by birds = 't' seconds.

The expression of distance more robin flew than the cardinal flew = $(r-c)t$

Now we need to find the  $(r-c)$ representing in the above expression.

Solution:

Now we can say that When two objects move with speed 'a' and 'b' with same amount of time and in the same direction then we can say that a-b will be the Relative speed of the 'a' with respect to 'b'.

From above expression we can say that;

$(r-c)$ represents Relative Speed of Robin with respect to Cardinal.
