Question

Туристы шли 3ч со скоростью 5 км/ч. За сколько времени они проехали бы это расстояние на велосипедах, двигаясь со скоростью 15 км/ч? Во сколько раз скорость движения туристов меньше скорости велосипеда?

Answer 1

1) 3•5=15км все расстояние
2)15:15=1час они бы ехали на велосипедах
3) 3:1=3 раза ответ в 3 раза

Answer 2

Calculating Time Taken to Travel

To calculate the time taken to travel a certain distance, we can use the formula:

time = distance / speed

Given that the tourists walked for 3 hours at a speed of 5 km/h, we can calculate the distance they covered using the formula:

distance = speed * time

Substituting the given values: distance = 5 km/h * 3 h = 15 km.

Time to Travel the Same Distance on Bicycles

Now, let's calculate the time it would take for the tourists to cover the same distance on bicycles, moving at a speed of 15 km/h.

Using the formula: time = distance / speed

Substituting the distance and speed values: time = 15 km / 15 km/h = 1 hour.

Comparison of Speeds

To find out how many times the speed of the tourists is less than the speed of the bicycles, we can use the formula:

speed ratio = speed of bicycles / speed of tourists

Substituting the given values: speed ratio = 15 km/h / 5 km/h = 3.

So, the speed of the tourists is 3 times less than the speed of the bicycles.

Therefore, the tourists would cover the distance in 1 hour on bicycles, and their speed is 3 times less than the speed of the bicycles.
