Answer:
- speed of the first bus: 36 2/3 miles per hour
- speed of the second bus: 73 1/3 miles per hour
Step-by-step explanation:
The second bus travels twice as fast, so will take half the time of the first bus. The second bus takes 3 hours less time, so that is half the time of the first bus.
The first bus's speed is (220 mi)/(6 h) = 36 2/3 mph.
The second bus's speed is twice that: 73 1/3 mph.

Answer:
-3
Step-by-step explanation:
divide -72 by 24.
-72 ÷ 24 = -3
Answer:
a) a +b= 13, ab= 40
b) length= 8m, width= 5m
Step-by-step explanation:
Perimeter of rectangle= 2(length +width)
Area of rectangle= length ×width
a) Perimeter= 26m
2(a +b)= 26
Divide both sides by 2:
a +b= 26 ÷2
a +b= 13 ----- (1)
Area= 40m²
ab= 40 ----- (2)
b) From (1): a= 13 -b ----- (3)
Substitute (3) into (2):
(13 -b)(b)= 40
Expand:
13b -b²= 40
b² -13b +40= 0
Factorise:
(b -5)(b -8)= 0
b -5= 0 or b -8= 0
b= 5 or b= 8
Substitute into (3):
a= 13 -5 or a= 13 -8
a= 8 or a= 5
Since the length is usually the longer side of the rectangle, the length and the width of the rectangular garden is 8m and 5m respectively.
Answer: 28
Step-by-step explanation: 2x+x=42 (equation i used to solve for Cody)
2x+x=42 (add the similar elements)
3x=42
(divide both sides by 3)
x=14 (cody)
Zane has twice the amount so double 14 to get 28
