Answer:
The distance the marina can travel = = 48 miles
Step-by-step explanation:
The rate going out against the current is = u - v = 20
The rate going out with the current is = u + v = 30
Let the distance traveled by the motorboat =
Total time the boat can travel = 4 hours
⇒ Total time = ( Time taken by boat to go against the current ) + ( Time taken by boat to go with the current )
⇒ 4 =
⇒ 4 =
⇒ 4 =
⇒ = 48 miles
This is the distance the marina can travel.
Answer:
Step-by-step explanation:
ΔJKL ~ ΔMNP
So, the sides of both of the triangles are proportional.
Taking proportionality of their sides.
=>
Cross Multiplying
20 * 30 = 25(4x-4)
600 = 100x - 100
Adding 100 to both sides
600+100 = 120x
700 = 100x
Dividing both sides by 100
700/100 = x
x = 7
well, Diego is 4 now, so by his 18th birthday that'll be 14 years later.
The answer is 5
Because-9+4= -5
-5 +10 = 5
