36 because if you add 21 + 15 you get 36. How by adding it all together. I hope this helped you bye
Answer:
The speed of the first train is 45 mph and the speed of the second train is 75 mph
Step-by-step explanation:
Let x represent the speed of the first train in mph. Since the second train, is 30 mph faster then the first, therefore the speed of the second train is (x + 30).
The first train leaves at 1:00 pm, therefore at 6:00 pm, the time taken is 5 hours. Therefore the distance covered by the first train at 6:00 pm = x mph * 5 hours = 5x miles
The second train leaves at 3:00 pm, therefore at 6:00 pm, the time taken is 3 hours. Therefore the distance covered by the second train at 6:00 pm = (x + 30) mph * 3 hours = (3x + 90) miles
Since the second train overtakes the first at 6:00 pm, hence:
3x + 90 = 5x
2x = 90
x = 45
Therefore the speed of the first train is 45 mph and the speed of the second train is 75 mph (45 mph + 30 mph).
8.75 x 37.5= ? Well all you do is have to line up the decimals and work it out! :) it's simple
Answer:
The range of a relation is the set of the second coordinates from the ordered pairs.
Step-by-step explanation:
The range of a relation from A to B is a subset of B. For Example: If A = {2, 4, 6, 8) B = {5, 7, 1, 9}. Let R be the relation 'is less than' from A to B.
