Justin is on a road trip. Over the past two days, he’s driven a total distance of 504 miles at an average speed of 56 miles/hour
irakobra [83]
Recall d  = rt, distance = rate * time.

now, he has a speed rate of 56 mph for a distance of 504

\bf d=rt\implies 504=56t\implies \cfrac{504}{56}=t\implies \stackrel{hours}{9}=t

so, at that speed the whole driving time is 9 hours then.  Ok, he drove 2 hours today, that means he drove 7 yesterday, 9 - 2.

how many miles is it for 7 hours at 56mph?  d = rt ---> d = 56 * 7

that many miles he drove yesterday.

Find the perimeter and the area of a rectangle with the sides 4 7/20 m and 6 2/3 m.
Simora [160]

9514 1404 393

Answer:

  • perimeter: 22 1/30 m
  • area: 29 m²

Step-by-step explanation:

The perimeter is given by the formula ...

  P = 2(L+W)

  P = 2(4 7/20 +6 2/3) = 2(10 +61/60) = 2(11 1/60)

  P = 22 1/30 . . . . meters

__

The area is given by the formula ...

  A = LW

  A = (4 7/20)(6 2/3) = (87/20)(20/3) = 87/3 = 29 . . . . square meters

The perimeter is 22 1/30 meters; the area is 29 square meters.
