Answer:

\bar v = 60\,mph

Step-by-step explanation:

The distance travelled by Lisa in the first four hours of her trip is:

\Delta s = \left(50\,mph)\cdot (4\,h)

\Delta s = 200\,mi

The distance remaining and her average speed are, respectively:

\Delta s_{R} = 440\,mi - 200\,mi

\Delta s_{R} = 240\,mi

\bar v = \frac{240\,mi}{4\,h}

\bar v = 60\,mph

OverLord2011 [107]

Answer:

247 cards

Step-by-step explanation:

Misha : Carlos = 9 : 4

Carlos = 76 cards

Misha = x cards

9 : 4 = x : 76

9/4 = x/76

Cross product

9 * 76 = 4 * x

684 = 4x

x = 684 /4

x = 171

Misha = 171 cards

how many cards do they have together?

Total cards altogether = Misha + Carlos

= 171 cards + 76 cards

= 247 cards

Total cards altogether = 247 cards
