Divide the miles already drove by 7 cause thats every 15 minutes what would be drove so mutiply that by 4 and get 68.57 >> 68.6 miles per hour !
Whats the problem? just substitute. For example: 3x-5 if x=4 so what you do is this; 3(4)-5=7
Answer:
135 is the correct answer
Step-by-step explanation:
6x^2-3x
substitution
x=5
6* (5*5) -3*5
6*25-3*5
150-15= 135
Distance is calculated by the square root of (x2-x1)^2 + (y2-y1)^2
We simply substitute the values into this formula
Square root of (3--5)^2 + (0-1)^2
Which is 8
