A train leaves boston at 2:00 pm. a second train leaves the same city in the same direction at 6:00 pm. the second train travels

AURORKA [14]

$\boxed {\boxed { \text {Distance = Speed x Time}}}$

<u>First Train:</u>
Time taken = 9 hours (2pm to 11pm)
Let the speed be x
Distance = Time x Speed = 9x

<u>Second Train:</u>
Time taken = 5 hours (6pm to 11pm)
Speed = x + 48
Distance = Time x Speed = 5(x + 48)

Since both the distance they traveled are the same, we equate the distance to solve for x.

<u>Solve for x:</u>
9x = 5(x + 48)
9x = 5x + 240
4x = 240
x = 60

<u>Find the speed:</u>
x = 60 mph
x + 48= 108 mph

Answer: The spend of the two trains are 60 mph and 108 mph.

Sarah can paint 2 square feet of fence in 10 minutes .Fill in the missing parts to tell how long it will take him to paint a fen

Kitty [74]

Answer:

Sarah will be able to paint <u>150 square feet</u> of fence in <u>12 hours and 50 mins</u>.

Step-by-step explanation:

Given:

Width of the fence = 6 feet

Length of the fence = 25 feet

Now we will first find the Area of the fence we get;

Area of the fence is length times width.

framing in equation form we get;

Area of the fence = $6\times25 = 150ft^2$

Now Given:

2 square feet fence painting = 10 mins

so 150 square feet fence painting = number of mins require to paint 150 square feet fence.

By using Unitary method we get;

number of mins require to paint 150 square feet fence. = $\frac{150\times10}{2} = 750\ mins$

Now we know 1 hour = 60 mins.

Number of hours = 750 mins

Again By using Unitary method we get;

Number of hours = $\frac{750}{60} =12.5$

Hence Sarah will be able to paint <u>150 square feet</u> of fence in <u>12 hours and 50 mins</u>.
