Answer:

Step-by-step explanation:

You really don't even have to calculate anything.

B can be reduced to 4/5 by dividing 24 by 6 and 30 by 6

C can be reduced to 1/15 by dividing 2 by 2 and 30 by 2

D can be reduced to 1/2.

The answer then is A

2 feet is 2 * 12 = 24 inches.

24/30 = 4/5. See B.

It most common to round to the hundredths place, this is two spaces after the decimal.

So look two spaces right - 0.17. If the third digit (in this case 6) is higher than 5 you round the number up if its not, keep it the same.

"6" is greater than five, so round it to about (or approximately) 0.18.

Two cars travel at the same speed to different destinations. Car A reaches its destination in 17 minutes. Car B reaches its dest

Goryan [66]

Answer:

speed of car A =Speed of car B=0.8 miles/minutes.

Step-by-step explanation:

We are given that speed of car A is equal to speed of car B.

Also let car A travels x miles.

and car B travels y miles.

Car A reaches its destination in 17 minutes.

this means that speed of car A is given by: $\dfrac{x}{17}$ miles/minutes ( since speed is defined as the ratio of distance and time).

Car B reaches its destination in 32 minutes.

This means that the speed of car B is given by: $\dfrac{y}{32}$ miles/minutes

as speed of both cars are equal this means:

$\dfrac{x}{17}=\dfrac{y}{32}$ ------(1)

Also we are given Car B travels 12 miles farther than Car A.

this means $y-x=12$

$y=12+x$ ------(2)

on using equation (1) and (2) we have:

$\dfrac{x}{17}=\dfrac{12+x}{32}\\ \\32x=17(12+x)\\\\32x=17\times12+17x\\\\32x-17x=17\times12\\\\15x=122\times17\\\\x=13.6$

Hence the speed of car A is 0.8 miles/minutes ( since x/17 is the speed of car A)

Speed of car B=0.8 miles/minutes.
