Answer 2

Problem Analysis

We are given that a motorcycle and a bus left a city simultaneously in opposite directions. After 4 hours, the distance between them was 572 km. The speed of the motorcycle is given as 96 km/h. We need to find the speed of the bus.

Solution

To find the speed of the bus, we can use the formula: speed = distance / time.

Let's calculate the speed of the bus:

1. The distance traveled by the motorcycle in 4 hours is: distance_motorcycle = speed_motorcycle * time = 96 km/h * 4 h = 384 km.

2. The distance traveled by the bus in 4 hours is: distance_bus = total_distance - distance_motorcycle = 572 km - 384 km = 188 km.

3. The speed of the bus is: speed_bus = distance_bus / time = 188 km / 4 h = 47 km/h.

Therefore, the speed of the bus is 47 km/h.

Solving Equations

Let's solve the given equations:

1. (267 - x) * 4 = 416 + 3023

Expanding the equation, we get:

1068 - 4x = 3439

Rearranging the equation, we get:

-4x = 3439 - 1068

-4x = 2371

Dividing both sides by -4, we get:

x = -2371 / -4

x = 592.75

Therefore, the value of x is approximately 592.75.

2. u * 8 = 4839

Dividing both sides by 8, we get:

u = 4839 / 8

u = 604.875

Therefore, the value of u is approximately 604.875.
