Question

Мотоцикл движется со скоростью U1=54км/ч, автобус-со скоростью U2=20м/с .Какое из этих транспортных средств движется с большой скоростью?

Answer 1

V1=54/3.6=15 м/с
v2=20 м/с
v2>v1
===========================

Answer 2

Comparison of Speeds

To determine which vehicle is moving at a higher speed, let's compare the speeds of the motorcycle and the bus.

The speed of the motorcycle is given as U1 = 54 km/h.

The speed of the bus is given as U2 = 20 m/s.

To compare these speeds, we need to convert them to the same unit. Let's convert the speed of the motorcycle from kilometers per hour (km/h) to meters per second (m/s).

Converting Motorcycle Speed

To convert the speed of the motorcycle from km/h to m/s, we can use the following conversion factor:

1 km/h = 1000 m/3600 s

Using this conversion factor, we can calculate the speed of the motorcycle in m/s:

54 km/h * (1000 m/3600 s) = 15 m/s

Therefore, the speed of the motorcycle is 15 m/s.

Comparison of Speeds

Now that we have both speeds in the same unit (m/s), we can compare them.

The motorcycle is moving at a speed of 15 m/s, while the bus is moving at a speed of 20 m/s.

Therefore, the bus is moving at a higher speed compared to the motorcycle.

Conclusion

In summary, when comparing the speeds of the motorcycle and the bus, we found that the bus is moving at a higher speed. The bus is moving at a speed of 20 m/s, while the motorcycle is moving at a speed of 15 m/s
