Two skiers are 30 kilometers apart and head towards each other. they meet in 2 hours. if the second skier is 5 kilometers per hour faster then the other, find the speed of each skier?

Speed of first skier = 5 km/h

Speed of second skier = 10 km/h

Step-by-step explanation:

Given:

Distance between skiers = 30 km

Time after which they meet = 2 hours

Second skier is 5 km/h faster than the first skier.

To find speed of each skier.

Solution:

Let the speed of first skier be in km/h =

Distance covered in km 2 hours will be =

Speed of second skier in km/h can be given as =

Distance traveled by second skier after 2 hours will be =   [Using distribution]

Since, the skiers were 30 km apart initially, so the total distance covered by both of them when they meet after 2 hours will be = 30 km

Thus, we have:

Solving for

Subtracting both sides by 10.

Dividing both sides by 4.

Speed of first skier = 5 km/h

Speed of second skier = = 10 km/h

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
