Stephanie draws a map of her neighborhood. She uses a scale in which 1 inch equals 5 miles. What distance on Stephanie's map should represent the 3 miles between her house and park? *

 M + 3n = 7 ; n = -2, 0 , 1

1

h

3.5x = 25 + 3x

Step-by-step explanation:

Let x be the speed in miles per hour of both red car and blue car,

We know that,

Distance = speed × time,

If time taken by red car = 3 hours,

Then the distance travelled by red car = 3x

Now, if the time taken by blue car = 3.5 hours,

Then the distance travelled by blue car = 3.5x

According to the question,

Distance covered by blue car = 25 miles + Distance travelled by red car

3.5x = 25 + 3x

Which is the required equation.
