In the formula d = r × t, if d equals 60 and t remains constant, which of the following is equivalent to r?

• A. 60/t
• B. 60t
• C. t/60
• D. d/t

Answer: (A)

The formula \( d = r \times t \) describes the relationship between distance (d), rate (r), and time (t). To isolate the variable \( r \), the equation can be rearranged. Since \( d \) is given as 60 and \( t \) is constant, you want to express \( r \) in terms of \( d \) and \( t \). Starting from the original formula, you can rearrange it to solve for \( r \): 1. Begin with the formula: \( d = r \times t \). 2. To isolate \( r \), divide both sides of the equation by \( t \): \[ r = \frac{d}{t} \] Substituting \( d = 60 \) into the equation gives: \[ r = \frac{60}{t} \] This shows that the appropriate expression for \( r \) in this scenario is \( \frac{60}{t} \). Thus, the correct response is represented by the choice that simplifies to \( \frac{60}{t} \), which is why the answer \( 60/t \) is indeed the correct equivalent expression for \( r \). The other

The formula ( d = r \times t ) describes the relationship between distance (d), rate (r), and time (t). To isolate the variable ( r ), the equation can be rearranged.

Since ( d ) is given as 60 and ( t ) is constant, you want to express ( r ) in terms of ( d ) and ( t ). Starting from the original formula, you can rearrange it to solve for ( r ):

1. Begin with the formula: ( d = r \times t ).

2. To isolate ( r ), divide both sides of the equation by ( t ):

[

r = \frac{d}{t}

]

Substituting ( d = 60 ) into the equation gives:

[

r = \frac{60}{t}

]

This shows that the appropriate expression for ( r ) in this scenario is ( \frac{60}{t} ).

Thus, the correct response is represented by the choice that simplifies to ( \frac{60}{t} ), which is why the answer ( 60/t ) is indeed the correct equivalent expression for ( r ). The other
