Solving 8 problems per minute, Fast Finn can finish his test in time. He was however, working faster, solving 10 problems per mi
mrs_skeptik [129]

Answer:

Number of problems = 240

Step-by-step explanation:

Let x be the number of questions and t be the time.

Given:

Average rate = 8 problems per minute

Fast Finn rate = 10 problems per minute

Fast Finn taken time = t - 6

We need to find the number of problems on the test paper.

Solution:

Average rate to solve test paper.

Average\ rate =\frac{Number\ of\ questions}{time}  

8 =\frac{x}{t}

t =\frac{x}{8} --------------(1)

Fast Finn rate to solve the test paper.

Average\ rate =\frac{Number\ of\ questions}{time}  

10 =\frac{x}{t-6}

Using cross multiplication rule.

x=10(t-6)

x=10t-60

substitute t =\frac{x}{8}  from equation 1.

x=10(\frac{x}{8}) -60

Rearrange the equation as:

x - \frac{5}{4}x = -60

\frac{4x-5x}{4}=-60

-\frac{x}{4} =  -60

Using cross multiplication rule.

x = 60\times 4

x = 240 problems.

Therefore, 240 problems were on the test.
