A cyclist rode 3.75 miles in 0.3 hours. How fast was she going in miles per hour?
At that rate, how long will it take her to go 4.5 miles?

1)speed=12.5 miles/hr

2)time=56.25hr or 0.36hr(i prefer this one..check explanation)

Step-by-step explanation:

speed=distance/time

s=3.75/0.3=12.5

speed is = 12.5 miles/hr

2nd part:

speed=distance/time

so time=speed*distance

: time=12.5*4.5=56.25hr(hard to believe the answer)

or

miles:hours

3.75:0.3

4.5:x

cross multiply

4.5*0.3/3.75=0.36

x=0.36hrs (answer is believeable)

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

pls mark as brainliest

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
