In day mode, Jirka enrolled: sleep 50%, learning 25% free time (fun + help at home) 25%. How many hours a day does he spend on each activity? - Bedrich and Adam
When Bedrich is as old as Adam today, Adam will be 14 years old. When Adam was as old as Bedrich, Bedrich was two years old today. How old are Adam and Bedrich today? - MO Z8-I-1 2018 Frank and David meet daily in the elevator. One morning, they found that if they multiply their current age, they get 238. If they did the same after four years, this product would be 378. Determine the sum of the current ages of Frank and David.

In our town there are three cinemas, which are named according to the compass points. About their opening hours it is known that: • every day at least one cinema is open, • if the southern cinema is open, then the northern cinema is not open, • the northe - Acceleration of a train
The train passes 700 m, braking with an acceleration of -0.15 m/s². How long does it break, and what is the final speed of the train if the initial was 55 km/h? - Car braking calculation
The car starts to brake with an acceleration of -6.5 m/s² and stops on the track at 45 m. What were the initial speed and braking time? - Driver
The car driver drove at 100 km/h saw the obstacle and began braking with a slowing of 5 m/s². What is the pathway's length to stop the car when the driver has registered the obstacle with a delay of 0.7 seconds? - Electricity blackout
On Tuesday at 6 o'clock, the electricity supply was interrupted at 156 h. On which day (1 = Monday, ... 7 = Sunday) and at what time was the electricity supply resumed? - Clock arc length Calculate the length of the arc, which will describe the endpoint of a longer hand 10 cm long wall clock after 20 minutes.

The first generation of microorganisms has a population of 13500 members. Each subsequent generation is 11/10 times the previous one. Find out how many generations will reach at least three times members of the first generation. - Days2minutes
Write a formula that converts x days to y minutes. The formula is: - Bank Deposit Annual Interest
Mr. Smith deposited CZK 50,000 a year in the bank at an annual interest rate of 4%. How much will pre-tax interest be after one year? - Age In 1960, my age was equal to the digits sum of the year of my birth. What is my age now?
- Car overtaking
A passenger car travels at a speed of 30 m/s; before it travels, a freight truck drives at a constant speed of 10 m/s. Within 30 meters of the truck, the driver of the car finds out that the truck can not overtake. That's why it starts braking with an acc - Two mass points
Two mass points start moving simultaneously in the same direction from the same location: the first point moves uniformly at a speed of 50 cm/s, and the second point moves with uniform acceleration from rest at an acceleration of 10 cm/s². Determine: a) t - Two bodies 2
Two bodies start moving simultaneously from the same place in the same direction. The first body moves with uniform acceleration with an initial velocity of 4 m/s and an acceleration of 0.5 m/s², while the second body moves with uniform deceleration with - Wall wallpaper time
Zofia decided to wallpaper one wall of her room. How long does he have to go to school if the wall dimensions are 3 m and 2.4 m? - Brakes
The braking efficiency of a passenger car is required to stop at 12.5 m at an initial speed of 40 km/h. What is the acceleration braking by brakes? - Two cars 6
Two cars leave the same place one after the other, 15 seconds apart. Both move with uniform acceleration from rest: the first car with an acceleration of 0.5 m/s², and the second car with an acceleration of 2 m/s². Determine: a) the time and distance at w - Ball acceleration distance
A ball placed on an inclined plane begins to move and reaches a speed of 1 m/s in 5 s. Assuming that the ball's motion is uniformly accelerated, determine the magnitude of its acceleration and the distance it travels in the given time.
