Let n be the speed of train b, and n-16 be the speed of train a. Then:
190/n-16=270/n
190n=270n-4320
80n=4320
n=54 mph
n-16=38 mph

Is the same as the one you just did.

keep in mind that, going against the current, the current's speed erodes speed from your regular speed, whilst if you're going with the current, the current's speed adds to it.

now, in this case, you row 5mph, going upstream you're only doing 3mph, whatever happened to the other 2mph?  well, the current speed eroded them, meaning the speed of the river is 2mph.

now, going downstream with the current, your regular speed is 5mph, and the current is 2mph, since the current adds to yours, then you're going 5 + 2, mph.

Need help pls help me will mark first

Answer:

angles 5,6 are supplementary

angles 7 and 4 are vertical angles

(one solution of many)

Step-by-step explanation:

Lets start with supplementary angles. those are two angles that add up to 180 degrees or make a straight angle. Two angles that fulfill this statement are 5 and 6 because 5 and 6 make a straight angle.

Now lets do vertical angles. Vertical angles are angles that are opposite of each. They are made by intersecting diagonals. One pair of angles that fulfill this are angles 7 and 4. if you can tell, they are opposite of each other.

supplementary= 5 and 6

vertical= 7 and 4

have a wonderful day!
