Question

Велосепидист проехал за 3 пятых часа проезал 7 целых 1 вторая келометров . Сколько километров проедет велосипедист ща 2 целых 1 вторая часа, если будет ехать с такой же скоростью?

Answer 1

1) 7 1/2 : 3/5=15/2 : 3/5= 12. 1/2 км/ч - скорость велосипедиста

2) 12. 1/2 * 2. 1/2=25/2 * 5/2=125/2=31 1/2 км проедет

Answer 2

Calculation of Distance Traveled

To calculate the distance traveled by the cyclist, we need to determine the speed at which the cyclist is traveling. We can do this by dividing the total distance traveled by the time taken.

Given: - Time taken: 3/5 hours - Distance traveled: 7 whole kilometers + 1/2 kilometer

To find the speed, we divide the distance traveled by the time taken:

Speed = Distance / Time

Let's calculate the speed first.

Calculating the Speed:

Distance = 7 km + 1/2 km = 7.5 km Time = 3/5 hours

Speed = 7.5 km / (3/5) hours

To divide by a fraction, we can multiply by its reciprocal:

Speed = 7.5 km * (5/3) hours

Now, let's calculate the speed:

Speed = 7.5 km * (5/3) hours = 12.5 km/h

Therefore, the cyclist is traveling at a speed of 12.5 kilometers per hour.

Distance Traveled in 2 1/2 Hours

Now, we need to calculate the distance the cyclist will travel in 2 1/2 hours, assuming they maintain the same speed.

Given: - Time taken: 2 1/2 hours (2 whole hours + 1/2 hour)

To find the distance traveled, we multiply the speed by the time taken:

Distance = Speed * Time

Let's calculate the distance traveled:

Speed = 12.5 km/h Time = 2 1/2 hours = 2.5 hours

Distance = 12.5 km/h * 2.5 hours

To multiply by a fraction, we can multiply the numerators and denominators:

Distance = (12.5 * 2.5) km

Now, let's calculate the distance:

Distance = 31.25 km

Therefore, if the cyclist continues to ride at the
