Answer:

Speed of train from station M = 85 miles per hour

Speed of train from station N = 90miles per hour

Step-by-step explanation:

Given that the distance between two points M and N is 380 miles

Suppose the speed of train M is x

So, the speed of train N is 5 + x

Formula to use:

distance = speed x time

For the train from point M

d = x * 2

d = 2x

For the train from point N

d = (5 + x) * 2

the above 2 distances plus 30 miles equals 380 miles

Equation:

2x + 2(x+5) + 30 = 380

2x + 2x + 10 + 30 = 380

4x + 40 = 380

4x = 380 - 40

4x = 340

x = 340/4

x = 85 mph for train M

Now put the value in the second train's speed

x + 5

85 + 5

= 90 mph for train N

8. Mohan wants to buy a trapezium shaped field.
mojhsa [17]

Answer:

<em>The length of the side along the river is 140 m</em>

Step-by-step explanation:

<u>Equations</u>

To solve the problem, we need to recall the area of a trapezium is:

\displaystyle A=\frac{b1+b2}{2}.h

Where b1 and b2 are the lengths of the parallel sides and h is the height of the trapezium.

The field to be bought by Mohan has a trapezium shape with a side along the road of side x and a side along the river of side 2x, as stated in the problem.

Knowing the height is h=100 m, and the area is 10500 m2:

\displaystyle \frac{x+2x}{2}\cdot 100=10500

Simplifying:

\displaystyle (3x)\cdot 50=10500

150x=10500

Dividing by 150:

x = 10500 / 150 = 70

x = 70 m

2x = 140 m

The length of the side along the river is 140 m
