Lily drove 354 miles in 6 hours. On average, how fast did she drive in hours per mile?

vagabundo [1.1K]

Answer: $\dfrac{1}{59}\ \text{hours per mile}$

Step-by-step explanation:

Given : Distance traveled by Lily= 354 miles

Time= 6 hours

Then,

$\text{LIly's rate in hours per mile}=\dfrac{6\text{ hours}}{354\text{ mile}}\\\\=\dfrac{1}{59}\ \text{hours per mile}$

Hence, the required speed of Lily = $\dfrac{1}{59}\ \text{hours per mile}$

Order of Operations

emmasim [6.3K]

Given:

$4 + 9 + 16 \div 4 - 8 -3 \times 5$

To find:

The number of possible solutions, if the Order of Operations did not exist.

Solution:

We have,

$4 + 9 + 16 \div 4 - 8 -3 \times 5$

Now,

Case 1:

$[4 + 9 + 16] \div [4 - 8 -(3 \times 5)]=29\div (4 - 8 -15)$

$4 + 9 + 16 \div 4 - 8 -(3 \times 5)=-\dfrac{29}{19}$

Case 2:

$[4 + 9 + 16] \div (4 - 8 -3) \times 5=29\div (-7\times 5)$

$4 + 9 + 16 \div (4 - 8 -3) \times 5=-\dfrac{29}{35}$

Case 3:

$4 + 9 + (16 \div 4) - 8 -(3 \times 5)=4+9+4-8-15$

$4 + 9 + (16 \div 4) - 8 -(3 \times 5)=-6$

Many more possibilities are there.

Therefore, there are more than 3 possible solutions.
