Ответ:
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.
