Answer:
The cost of three 2/3 pounds is $4.
Step-by-step explanation:
Here, given:
The cost of 1 pound of shrimp = $6
Now, the dish requires the amount of shrimp = 2/3 pounds.
Here: 1 pound shrimp = $ 6
or, the cost of 2/3 pound = $ 4
Hence, the cost of three 2/3 pounds is $4.
By definition, whole numbers will never be negative. They are the numbers we count with but include 0. -4 is not a whole number.
Step-by-step explanation:
Let the original speed of the train be x km/h.
Time taken to cover a distance of 360 km = 360/x hours.
New speed of the train = (x+5) km/h.
Time taken to cover a distance of 360 km at new speed = 360/x+5 hours.
Since, the train takes 1 hour less time,
∴360/x - 360/ x+5 = 1
⇒360 (5) = x² + 5x
⇒1800 = x² + 5x
⇒x² + 5x - 1800 = 0
⇒x² + 45x - 40x - 1800 = 0
⇒x (x+45) - 40( x +45) = 0
⇒(x+45) (x-40) = 0
⇒x = (-45), 40
But since speed cannot be in negative.
∴x = 40 km/hr.
Hence, the original speed of the train is 40 km/h.
