Answer:
- 34.5 miles in 46 minutes
- 45 miles in 1 hour
Step-by-step explanation:
The speed of the car in miles per minute is ...
(2 1/2 miles)/(3 1/3 minutes) = (5/2)/(10/3) miles/minute
= (5/10)(3/2) miles/minute = 3/4 miles/minute
Then in 46 minutes, the car will travel ...
(3/4 miles/minute)(46 minutes) = (138/4) miles = 34 1/2 miles
The car will travel 34 1/2 miles in 46 minutes.
__
In 60 minutes, the car will travel ...
(3/4 miles/minute)(60 minutes) = 45 miles
The car will travel 45 miles in 1 hour.

Answer:
8
Step-by-step explanation:
Height, h = 17
Let :
Width = x
Length = 2x + 4
Volume = 2720 in³
Volume of rectangular prism = Length * width * height
2720 = 17 * x * (2x + 4)
2720 = 34x² + 68x
34x² + 68x - 2720 = 0
x² + 2x - 80 = 0
x² + 10x - 8x - 80 = 0
x(x + 10) - 8(x + 10)
(x + 10) = 0 or (x - 8) = 0
X = - 10 or x = 8
Width can't be negative
Hence, width, x = 8
