Question

Велосипедист проехал расстояние 51 км за 4 ч, а мотоциклист проехал расстояние 186 км за 5 ч. У кого из них скорость больше и на сколько? ПОМОГИТЕ СРОЧНО!ЗАРАННЕ СПАСИБО!!!

Answer 1

Вел = 51/4  км/ч
мот  186/5 км / ч
 сравним
 255/20  и 744/20
255- 744 = 489, у мот скорость больше на 489/20 чем у велос

Answer 2

51/4=12,75км/ч
186/5=37,2км/ч 
37,2км/ч≥12,75км/ч 

Answer 3

Calculation of Speed

To determine which of the cyclist or the motorcyclist has a higher speed, we need to calculate their respective speeds.

The formula to calculate speed is:

Speed = Distance / Time

Let's calculate the speeds of the cyclist and the motorcyclist.

For the cyclist: - Distance = 51 km - Time = 4 hours

Speed of the cyclist = 51 km / 4 hours = 12.75 km/h For the motorcyclist: - Distance = 186 km - Time = 5 hours

Speed of the motorcyclist = 186 km / 5 hours = 37.2 km/h

Comparison of Speeds

Now, let's compare the speeds of the cyclist and the motorcyclist.

- The cyclist has a speed of 12.75 km/h. - The motorcyclist has a speed of 37.2 km/h.

Therefore, the motorcyclist has a higher speed than the cyclist by 24.45 km/h.
