Calculate the unit rate: write your answer as a decimal 1/2 mile in ever 1/3 hour

Alexandra [31]

Answer:

$unit \: rate = \frac{distance}{time}$

unit rate is similar to speed / velocity:

$unit \: rate = \frac{ (\frac{1}{2} )}{ (\frac{1}{3})} \\ \\ = \frac{1}{2} \div \frac{1}{3} \\ \\ = \frac{1}{2} \times \frac{3}{1} \\ \\ = > { \boxed{ \boxed{unit \: rate = \frac{3}{2} \: miles \: per \: hour}}}$

[unit rate must have units including per <time> ]

Evaluate the expression into simplest form

sattari [20]

Work out the top subtraction first:

3/9 - 8/12

= 1/3 - 2/3

= 1/3

and the bottom part:-

3/8 * 2 = 6/8 = 3/4

so now we divide -1/3 by 3/4

= -1/3 * 4/3 = -4/9

Two hoses from two different taps are used to fill a fishpond. The first hose alone

Paraphin [41]

Answer: 12 minutes

Step-by-step explanation:

Two rates for hoses A and B. FP is the Fish Pond.

A = 20 min/FP or (1/20)FP/min

B = 30 min/FP or (1/30)FP/min

The time in minutes, X, to fill one FP:

1FP = X*((1/20)FP/min) + X*((1/30)FP/min)

1FP = X*(1/20+1/30)FP/min

1FP = X*(2.5/30)FP/min

X = 12 minutes
