Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hours. One car travels 5 miles per
horrorfan [7]

The speed of slower car is 45 mph and faster car is 50 mph.

Step-by-step explanation:

Given,

Distance covered by both cars = 190 miles

Time taken by both of them = 2 hours

Let,

x be the speed of slower car.

Speed of faster car = x+5

Combined speed = x+x+5 = 2x+5

We know that;

Distance = Speed * Time

190=(2x+5)*2\\190=4x+10\\4x=190-10\\4x=180\\

Dividing both sides by 4

\frac{4x}{4}=\frac{180}{4}\\x=45

Speed of slower car = 45 miles per hour

Speed of faster car = 45+5 = 50 miles per hour

The speed of slower car is 45 mph and faster car is 50 mph.

Keywords: speed, distance

Kazeer [188]

Answer:

Height of the building = 50.8 ft

Step-by-step explanation:

A person and a building are casting the shadows at the same time of the day.

Triangles formed by the person and his shadow and the building and its shadow will be similar.

Therefore, corresponding sides of the similar triangles will be proportional.

\frac{x}{28}=\frac{5.8}{3.2}

x = \frac{5.8\times 28}{3.2}

x = 50.75

x ≈ 50.8 ft
