Algebraic equation solving?

Question

Answer 1

........d

v = ---- ⇒ vt = d

........t

......................d

...........⇒ t = -----

......................v

Substitute d = 10 and v 2.5

......................10

...........⇒ t = ------

......................2.5

...........⇒ t = 4..................ANS

Answer 2

You are given an equation:

v = d/t

You are given two unknowns:

d = 10

v = 2.5

Substitute what you know and solve for the unknown:

2.5 = 10/t

Multiply both sides by t:

2.5t = 10

Divide both sides by 2.5:

t = 10/2.5

Simplify:

t = 100/25

t = 4
