Question

I need it done du the end of the day Please please

Answer 1

Answer:

1). Options (B) and (E)

2). First train is going faster than the second train.

Step-by-step explanation:

1). Rate of 2 gallons of vinegar = $3

   Therefore, per gallon rate of vinegar = $\frac{3}{2}$ = $1.5

   In $3 quantity of vinegar chef will get = 2 gallons

   Therefore, quantity of vinegar chef will get in $1 = $\frac{2}{3}$ gallons

Option (A).

Price of 4 gallons = 4 × $1.5 = $6.00

False.

Option (B)

Price of 1 gallon = $1.50

True

Option (C)

Price of 30 gallons = 30 ×$1.5 = $45    

False.

Option (D)

In $2 number of gallons of vinegar chef will get = $\frac{2}{3}\times 2=\frac{4}{3}$ gallons

False

Option (E)

Number of gallons of vinegar chef gets in $1 = $\frac{2}{3}$

True

Therefore, Options (B) and (E) are the correct.

2). Speed = $\frac{\text{Distance}}{\text{Time}}$

For first train,

Speed = $\frac{30}{\frac{1}{3}}$

            = 90 miles per hour

For second train,

 Speed = $\frac{20}{\frac{1}{2}}$

             = 40 miles per hour

 Since, 90 miles per hour > 40 miles per hour

 First train is going faster than the second train.
