Answer:

plane: 850 mph
jet stream: 150 mph

Step-by-step explanation:

The speed of the plane is the average of the two speeds. The speed of the jet stream is half their difference.

against: (5600 mi)/(8 h) = 700 mi/h

with: (4000 mi)/(4 h) = 1000 mi/h

Plane's speed = (700 + 1000)/2 mi/h = 850 mi/h

jetstream speed = (1000 -700)/2 mi/h = 150 mi/h

The rate of the jet in still air is 850 mi/h; the rate of the jetstream is 150 mi/h.

A chemist mixed 5 mL of Solution A with every 3 mL of Solution B to make a new solution

Nana76 [90]

Answer:

5:3

Step-by-step explanation:

Given that the chemist mixed 5 mL of Solution A with every 3 mL of Solution B to make a new solution with a new concentration.

So, the amount of Solution A in the mixture, a = 5 mL

The amount of Solution B in the mixture, b = 3 mL

Therefore, the ratio of Solution A to Solution B in the new solution with the same concentration is a:b=5:3.

Hence, the required ratio for the same concentration is 5:3.

Please note that none of the given options matched.
