m= miles   s=speed (MPH)    m/s=miles  240/45=5.333 hours

  Hours * minutes in an hour   5.33 * 60= 319.8

The answer is 320 minutes.

v=\frac{d}{t}\\\\v-velocity;\ d-distance;\ t-time\\-------------------------\\v=\frac{d}{t}\ \ \ \ |multiply\ both\ sides\ by\ t\\vt=d\ \ \ \ |divide\ both\ sides\ by\ v\\\\t=\frac{d}{v}\\------------------------

v=45\ mph;\ d=240\ mi\\\\t=\frac{240}{45}=\frac{240:15}{45:15}=\frac{16}{3}\ (h)\\\\1h=60min\\\\therefore\\\\t=\frac{16}{3}\cdot60min=16\cdot20min=\boxed{320min}

f(x) = 3(x+2)

f(-3) = 3(-3+2)

= 3(-1)

= -3

What fraction of 3 2/5 is 9 7/8
yanalaym [24]

Answer:

  395/136

Step-by-step explanation:

(9 7/8)/(3 2/5) = (79/8)/(17/5) = (79/8)(5/17) = 395/136

Since 9 7/8 is larger than 3 2/5, it is an improper fraction.
