Mike hiked to a lake in 4.5 hours at an average rate of 2

aleksandrvk [35]

Answer:

It took Pedro <em>3.81 hours</em> to reach the lake.

Step-by-step explanation:

Time taken by Mike to hike a lake = 4.5 hours

Average rate of Mike while hiking the lake = $2\frac{1}{5}\ miles/hr$

Formula for distance can be seen as:

$Distance = Speed\times Time$

Distance traveled by Mike = $4.5 \times 2\frac{1}{5} = 4.5\times \frac{11}{5} = 9.9\ miles$

Rate of Pedro while hiking the same distance = $2\frac{3}{5}\ miles/hr = \frac{13}{5}\ miles/hr$

Given that, Pedro also travels the same distance.

And we have to find the Time.

$Time = \dfrac{Distance}{Speed}$

$Time = \dfrac{9.9}{\frac{13}{5}}\\\Rightarrow Time = \dfrac{9.9\times 5}{13} = \bold{3.81\ hours}$

It took Pedro <em>3.81 hours</em> to reach the lake.

You sell instruments at a Caribbean music festival. You earn $326 by selling 12 sets of maracas, 6 sets of claves, and xx djembe

ELEN [110]

Answer: An equation we can use to find the number of djembe drums you sold be

$12m+6c+dxx=$326$

Step-by-step explanation:

Let price of maracas be m

Let the price of claves be c

Let the price of djembe drums be d

Number of maracas = 12 sets

Number of clavas = 6 sets

Number of djembe drums be xx

Total earned amount = $326

According to question,

$12m+6c+dxx=$326$

Hence, an equation we can use to find the number of djembe drums you sold be

$12m+6c+dxx=$326$
