Karissa ->. Distance = speed x time
Take the distance she travels to be x
X = 17t
Alexandra -> she would meet karissa at 261 - the x miles karissa travelled hence we get the equation
(261 - x ) = 12t
Rearrange so x is the subject
X = 261 - 12t
Next set the two equations equal to each other so you get
17t = 261 - 12t
Now solve for t
29t = 261
Divide each side by 29 To get the Value of t
t = 9 hours ( remember to take the units into account)
First, turn it into a multiplication problem by multiplying by the reciprocal of the divisor. Then, you can cancel common factors in the numerator and denominator to make things easier to work with. Finally, multiply<span> to get your final answer!</span>
What does the picture say It wont load. i would appreciate if you explained it
The formula for the surface area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.
