360 km (rider b)
Step by-step explanation:
(if they are going at a constant speed you can choose any point)
find how fast rider a is going:
60/2 = 30 km/h
find how fast rider b is going:
72/3 = 24 km/h
30 km/h for 15 hours = 30 x 15 = 450 km (rider a)
24 km/h for 15 hours = 24 x 15 = 360 km (rider b)

Answer:
The number is 112
Step-by-step explanation:
Let the number be 'x'
![\sf \dfrac{x}{14}=8\\\\\text{Multiply both sides by 14}\\\\ \dfrac{x}{14}*14=8*14\\\\](https://tex.z-dn.net/?f=%5Csf%20%5Cdfrac%7Bx%7D%7B14%7D%3D8%5C%5C%5C%5C%5Ctext%7BMultiply%20both%20sides%20by%2014%7D%5C%5C%5C%5C%20%5Cdfrac%7Bx%7D%7B14%7D%2A14%3D8%2A14%5C%5C%5C%5C)
<h3> x = 112</h3>
Answer:
L = 5S - 3
length of long side = 134.5 ft
length of short side = 27.5 ft
Step-by-step explanation:
L = 5S - 3
2L + 2S = 324 (keyword: enclose)
2(5S - 3) + 2S = 324
10S - 6 + 2S = 324
12S = 324 + 6 = 330
Thus S = 330/12 = 27.5 ft
Thus L = 5(27.5) - 3 = 134.5 ft
