Answer:
122 km/h
138 km/h
Step-by-step explanation:
distance = speed * time
One bus travels 16 km/h slower than the other
(s * 2) + (s - 16)2 = 520
2s + 2s - 32 = 520
4s = 552
s = 552/4
s = 138 km/h
s - 16 = 122 km/h
Answer:
150 feet would be first point when they both fall down.
Step-by-step explanation:
As Justin falls down every 30 feet and Mike falls down every 25 feet.
In order to find the first point when Justine and Mike both would be fallen, we need to determine the Least Common Multiple of L.C.M of 25 and 30.
In order to determine the Least Common Multiple of L.C.M of 25 and 30, first we need to list down some of the multiples of 25 and 30 until we find the lowest shared multiple of 25 and 30.
25: 25 50 75 100 125 150
30: 30 60 90 120 150
So, it is clear that the lowest shared multiple of 25 and 30 is 150. So, 150 will be our Least Common Multiple.
Therefore, 150 feet would be first point when they both fall down.

First element of the first ordered pair (-5, 5) is -5. First element of the second ordered pair (0, 5) is 0. First element of the third ordered pair (5, 5) is 5. So, the set made up of the first elements of the ordered pairs is {-5, 0, 5} and hence it is the domain.
