What kind of number does it have to be?
Answer:
106 km / hour
Step-by-step explanation:
Givens
Total time: 6 hours
Total distance: 1356 km
First bus rate: r
Second bus rate: r - 14
Formula
d = r * t
Solution
r*6 + (r - 14)*6 = 1356 Remove the brackets
6*r + 6*r - 84 = 1356 Add like terms
12r - 84 = 1356 Add 84 to both sides
12r + 84 - 84 = 1356-84 Combine
12r = 1272 Divide by 12
r = 1272/12
r = 106 km/hr
The correct answer is the second option :)
$9.60 because 4 times 3 is 12 so that’s 12 pens right there in 3 groups of 4 which 2.25 is the cost for one romp so 2.25 times 3 is 6.75 and u need 15 so 15-12 is 3 so u need 3 more and one pen cost 0.95 times 3 is 2.85 so that plus 6.75 is your answer for your profit of $9.60
P= 2L + 2W
P= (2+2ft) + (18+18in)
P= 4ft + 36in
12in = 1 ft
36in = 3ft
4ft + 3ft = 7ft
