A horse can run 1 3/8 of a mile in 1 3/5 minute. How long does it take the horse to run 1 mile?

So what i would personally do first is convert the fractions into decimals.

1 3/8= 11/8= 1.375    of a mile  

1 3/5= 8/5 =1.6         of a minute

Now we find the rate of change

Answer:

...

against the wind, an airplane travels 3640 km in 7 hours.

with the wind, the same plane travels 6000 km in 6hrs.

...

let speed of plane in still air be x mph

speed of wind be y mph.

..

t=d/r

..

against wind speed = x-y mph

with wond speed = x=y mph

...

3640/(x-y)=7

3640 = 7x-7y

/7

520=x-y.....................1

...

6000/x+y = 6

6000 = 6x+6y

/6

1000=x+y.....................2

...

Add (1) & (2)

2x=1520

/2

x=760 mph speed of plane in still air

...

plug value of x in 2

1000=760+y

100-760=y

240 = y

240 mph speed of wind

Step-by-step explanation:

The slope is found by

m= (y2-y1)/(x2-x1)

Andrew [12]

Answer:she has 120 apples left.

Step-by-step explanation:

Total number of apples that Lexi had in her basket to sell is 300.

If she dropped 122 apples on the ground because she can't use them and sell them, then the number of apples that she has left for sale is

300 - 122 = 178

If then after she sells 58 apples, the number of apples that she has remaining would be

178 - 58 = 120 apples

(3-20i)-(14+6i)-(8-2i)
ollegr [7]

Because there are parentheses we distribute the negative signs:

3 - 20i + (-14) - 6i + (-8) + 2i

Next combine like terms:

3 + (-14) + (-8) and -20i - 6i + 2i

-19 -24i
