The question is incomplete. The complete question is :
A man travels by a car from town A to town B, a total distance of 100 km at an average speed of x km/h. he finds that the time for the journey would be shorter by 25 minutes if he increases his average speed by 12km/h. Find x ?
Solution :
It is given the that the distance between town A and B is = 100 km
His initial average speed is = x km/h
His increased average speed is = 12 km/h
Time is shortened by = 25 minutes
So according to the question,
x-12 = 2500
x = 2512
Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
The figure is a parallelogram.
Consecutive angles are supplementary ( sum to 180° ) , then
x + 65° = 180 ( subtract 65° from both sides )
x = 115°
Opposite angles are congruent , then
y = 65°
z = x = 115°
Answer:
<h2>x = 1</h2>
Step-by-step explanation:
Look a t the picture.
The triangles on the picture are similar.
Therefore the sides are in proportion:
<em>cross multiply</em>
<em>divide both sides by 40</em>
Answer:
720 = x +133+138+148+95+105
x = 101
2.17720 × 10^2 is the answer
