A train can travel 1136 miles in 4 hours. what is the unit rate that this train is traveling per hour? _____ miles per hour
Answers
Good Morning
4hours .........1136 miles
1 hour ...........x
Cross-Multiply
4x= 1136*1
4x= 1136
x= 1136/4
x= 284
The train is traveling 284 miles per hour
I hope that's help !
Happy Sunday :)
Final answer:
To find the unit rate of the train's speed, divide the total distance traveled by the total time taken.
Explanation:
To calculate the unit rate at which the train is traveling per hour, you can apply a straightforward formula: divide the total distance covered by the total time taken. In this specific instance, the train covered a distance of 1136 miles within a time frame of 4 hours.
So, the unit rate for the train's speed is determined as follows:
Total distance traveled (1136 miles) divided by the total time taken (4 hours) equals 284 miles per hour.
This unit rate, expressed as 284 miles per hour, is a crucial metric for assessing the speed at which the train is moving. Understanding unit rates is valuable not only in transportation but also in various fields like economics, physics, and everyday calculations where quantities are compared with respect to time.

Answer:
2.68 units
Step-by-step explanation:
We are given that a rectangular box has dimensions 4 by 5 by 2.
We have to find that how much each dimension of the original box was increased to create the new box
Let x be the increased value in each dimension
We know that volume of rectangular box=lbh
Volume of original box==40 cubic units
Volume of new box =
Dimension of new box=
Volume of new box=240
By graph we get
x=2.679
Round to two decimal places then we get
x=2.68
Hence, each dimension was increased by 2.68 units

Answer A (x=-6 is an extraneous solution)
√(-3x-2)=x+2
==>-3x-2>=0
==>x<= -2/3
So -3x-2=(x+2)²
==>-3x-2=x²+4x+4
==>x²+7x+6=0
==> (x=-6) or (x=-1)
if x=-6 then
√(-3*(-6)-2)=√16=4
-6+2=-4
False 4≠-4
if x=-1
√(-3*(-1)-2)=√1=1
-1+2=1

Step-by-step explanation:
a.h/2 = 20
a.h = 40
2/5h.h = 40 (because a = 40%h)
h^2 = 100
h = 10
a = 4
