The teacher prepares 2.50 liters (L) of a salt solution for a class experiment. How many quarts (qt) are in 2.50 L? (1 quart =0.943 liters)

Answers

Answer 1
Answer:

Answer

2.65 quarts

Explanation

1 quart = 0.943 liters

To find the how many quarts are there in 2.50 litres we divide the 2.50 litres with 0.943 litres.

Number of quarts = 2.50/0.943

= 2.651113468

To the nearest hundredths the answer = 2.65 quarts
Answer 2
Answer:

the answer would be 2.65 quarts

Assume it takes 7.00 minutes to fill a 30.0 gal gas tank. (a) Calculate the rate at which the tank is filled in gallons per second. (b) Determine the rate at which the tank is filled in cubic meters per second. (c) Determine the time interval, in hours, required to fill a 1.00 m^3 volume at the same rate. ( 1 US gal = 231 in.^3)

Answers

a)
R1 = 30/(7*60)
We are multiplying 7 with 60 because there are 60 seconds in 1 minute.
R1 = 30/420 = 0.0714 gallons/second

b) For this we need to express gallons to cubic meters.
1 gallon = 0.003785 m^3
R2 = 0.0714*0.003785 = 0.00027 m^3/s

c) V = R2*t    where V is volume of some tank.
which means that
t=V/R2    
t =  3698.8s   or 
t = 1.0274 hours

A car travels 10 miles East in 30 minutes. What is its velocity in miles per hour?

Answers

30min=30/60hr=0.5hr

velocity=distance/time=10mile/0.5hr=20 miles per hour East

There are 60 minutes in an hour so 30 minutes is 0.5 hour.

Velocity is equal to displacement / time

= 10 miles East / 0.5 hour

= 20 miles per hour East
