Question

The goals against average (A) for a professional hockey goalie is determined using the formula A=60(g/2). In the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes. Which is an equivalent equation solved for g?

A) At/60=g
B) A/60t=g
C) 60A/t=g
D) 60At=g

Answer 1

g=at/60

Explanation:

Answer 2

g = At/60

Explanation:

Given:

A = 60(g/t)

60(g/2) is a mistake in the question which the question has corrected in the comments)

A is the average for a professional hockey goalie.

g is the number of goals scored against the goalie.

t represents the time played in minutes.

Finding 'g':

A = 60(g/t)

can be written as A = (60*g)/t

Multiplying by 't' on both sides:

At = (60*g)*t/t

At = 60*g

Dividing by '60' on both sides:

At/60 = 60*g/60

At/60 = g

⇒ g = At/60
