Don't need the answer, just how you would solve this:Tobin rows 2 miles per hour faster than her opponent. If it takes Tobin 30 minutes to finish a race, and it takes her opponent 45 minutes to finish the same race, how fast does Tobin row?
(A) 4 mph
(B) 5 mph
(C) 6 mph
(D) 30 mph

Answers

Answer:

(C) 6 mph

Step-by-step explanation:

Given,

The time taken by Tobin = 30 minutes,

While, the time taken by her opponent = 45 minutes,

So, the ratio of the time taken by tobin and her opponent = 30 : 45

$\because speed\propto (1)/(time)$

Thus, the ratio of speed of tobin and her opponent = $(1)/(30):(1)/(45)$

= 45 : 30

= 3 : 2

Suppose speed of tobin = 3x and speed of opponent = 2x

Where, x is positive real number,

Difference in speed = 3x - 2x = x

According to the question,

x = 2 miles per hour,

Hence, the speed of Tobin = 3x = 6 miles per hour.

Option (C) is correct

d = x * 45 opponent
d = ( x + 2) *30 Tobin
x * 45 = ( x + 2) *30
x* 15 = 60
x = 4
x + 2 = 6 mph

David recorded his finishing time, in seconds, for each time he ran the 100 m race during one track season. What was the median of his finishing times?11. 9 11.9 12.0 12.1 12.1 12.2 12.3 12.4 12.4

Answers

The median is 12.1 because it is the center number in the sequence. This only applies if the numbers are in order from least to greatest, and also if there are a even number of numbers in the sequence you must take the average of the two center ones because there is no center one.

What is 1 whole 1/4 subtract to
1/3

Answers

1 whole and 1/4 substracted to 1/3 can be written as:

1 1/4 - 1/3 =
= 5/4 - 1/3

We have to find a common denominator which is 12:

5/4 = 15/12
1/3 = 4/12

So now we just substract numerators:

15/12 - 4/12 = 11/12
