Brianna left the bookstore traveling 32 mph. Then 3.2 hours later, Sonya left traveling the same direction at 44.8 mph. How long

Lostsunrise [7]

Answer:

8 hours

Step-by-step explanation:

Let t hours be the time needed Sonya to catch up Brianna.

Sonya:

Time = t hours

Rate = 44.8 mph

Distance $=D_S$ miles

Brianna

Time $=t+3.2$ hours

Rate = 32 mph

Distance $=D_B$ miles

Note that $D_S=D_B,$ because Sonya must catch up Brianna.

Use formula $D=r\cdot t$

Hence,

$44.8t=32(t+3.2)$

Solve this equation:

$44.8t=32t+32\cdot 3.2\\ \\44.8t-32t=102.4\\ \\12.8t=102.4\\ \\t=8$

Pawan is 10 years older than Arav. 5 years ago one seventh of pawan's age was equal to one fifth of Arav's age. Find their prese

Marat540 [252]

Answer:

Arav is 30 and Pawan is 40

Step-by-step explanation:

We can call Arav's age x and Pawan's age x + 10, therefore we can write the following equation:

1/7((x + 10) - 5) = 1/5(x - 5)

1/7(x + 5) = 1/5(x - 5)

5(x + 5) = 7(x - 5)

5x + 25 = 7x - 35

-2x = -60

x = 30 so x + 10 = 40
