James drives a distance of 320 miles in 4 hours. What was his speed?
A. 80 mi/min
B. 80 mi/hr²
C. 80 km/hr
D. 80 mi/hr
Answer: D
Step-by-step explanation:
because 320/4 = 80 mi/hr because it can not km or min and hr^2 would not make any sense
James will cover 320 miles in 4 hours with the speed of 80 miles/hour.
What is speed?
Speed is the distance traveled per unit of time. The speed is given by distance/time.
What will be the speed of James?The distance travelled by James is 320 miles in 4 hours.
Divide distance by time to get the speed of James.
320/4=80.
The unit of distance was miles and of time was hour so the unit of speed will be miles/hour.
Therefore, the speed of James will be 80 miles/hour which is option D.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 400 feet. Determine the flag's length and width if the length is 80 feet greater than the width.
Answer:
Length-140 ft
Width-60 ft
Step-by-step explanation:
I tried many different combinations
Answer: 120 ft
Step-by-step explanation:
So the equation we start off with is
2l+2w=400 in this situation
Since we know one length is 80,
2l would be 160.
So now we have 160+2w=400
Now we can use the perimeter to find the width now that we know the 2l.
400-160=2w
2w=240
240÷2
W=120

Step-by-step explanation:
1) Let x represent the price of Tacos and y represent the price of Burrito. You where charged $4.80, hence:
2x + 2y = 4.80; Dividing through by 2:
x + y = 2.4 (1)
Your friend was charged $4.00, hence:
3x + y = 4.00 (2)
Solving equation 1 and 2 simultaneously by subtracting equation 2 from equation 1:
2x = 1.6
x = 0.80
Put x = 0.8 in equation 1:
0.8 + y = 2.4
y = 1.60
The cost of each tacos is $0.80 and the cost for each burritos is $1.60
2) Let x represent the smaller number and y the bigger number, hence:
y - x = 16 (1)
Also:
y = 4x - 5;
y - 4x = -5 (2)
Subtract equation 2 from equation 1 to solve simultaneously:
3x = 21
x = 7
Put x = 7 in equation 1:
y - x = 16
y - 7 = 16
y = 23
The greater number is 23 and the smaller number 7
