Answer:
12 inches
Step-by-step explanation:
The storage bin is in the shape of a rectangular prism.
Its volume is 5400 cubic inches and its base area is 450 square inches.
The volume of a rectangular prism is given as:
V = L * W * H
where L = length
W = width
H = height
The product of the length and width gives the base area of the rectangular prism:
A = L * W
This implies that:
V = A * H
=> 5400 = 450 * H
H = 5400 / 450
H = 12 inches
The height of the bin is 12 inches.
Answer:
Jennifer's speed is 2.4 miles/hour
Kamlee's speed is 2 miles/hour
Step-by-step explanation:
To find their speed,
Speed can be determined from the formula below,
Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)
For Jennifer,
Distance = 4/5 miles
Time = 20 mins (Convert to hour)
∴Time = (20/60) hour = 1/3 hour
Hence,
Hence, Jennifer's speed is 2.4 miles/hour
For Kamlee,
Distance = 5/6 miles
Time = 25 minutes (Convert to hour)
Time = (25/60) hour = 5/12 hour
Hence,
Hence, Kamlee's speed is 2 miles/hour
Answer:
30 mph
Step-by-step explanation:
Let the morning speed be represented by s.
Then the total distance drivern is 310 mi and this is equal to
5s + 4(s + 10):
5s + 4s + 40 = 310, or
9s = 270
Solving for s, we get s = 270/9 = 30
Then s + 10 = 40
He drove 30 mph in the morning and 40 mph in the afternoon.
Check: (30 mph)(5 hrs) + (40 mph)(4 hrs) = 310 miles. CORRECT
