Question

Турист шёл пешком 5 1/3 ч. со скоростью 4 1/8 км/ч и ехал на велосипеде 1 7/15 ч. со скоростью 12 1/2 км/ч.КАкое расстояние больше:то,которое турист преодолел пешком,или то,которое он проехал на велосипеде,и на сколько км.

Answer 1

Пешком 
S= 5 1/3 * 4 1/8  = 16/3 * 33/8 = 22 км
на велосипеде
S = 1 7/15 * 12 1/2 = 22/15 * 25/2 = 55/3 = 18 1/3
расстояние пешком больше на 3 2/3
22 - 18 1/3 = 21 3/3 - 18 1/3 = 3 2/3

Answer 2

Problem Analysis

The problem states that a tourist walked for 5 1/3 hours at a speed of 4 1/8 km/h and rode a bicycle for 1 7/15 hours at a speed of 12 1/2 km/h. We need to determine which distance is greater: the distance the tourist walked or the distance the tourist rode the bicycle, and by how many kilometers.

Solution

To find the distance the tourist walked, we can multiply the time walked by the speed: Distance walked = Time walked * Speed walked

To find the distance the tourist rode the bicycle, we can multiply the time ridden by the speed: Distance ridden = Time ridden * Speed ridden

We can then compare the two distances to determine which one is greater.

Calculation

Let's calculate the distance walked and the distance ridden:

Distance walked: Time walked = 5 1/3 hours Speed walked = 4 1/8 km/h

Distance walked = (5 1/3) * (4 1/8) km

Distance ridden: Time ridden = 1 7/15 hours Speed ridden = 12 1/2 km/h

Distance ridden = (1 7/15) * (12 1/2) km

Now, let's calculate the distances:

Distance walked = (16/3) * (33/8) km = 176/3 km Distance ridden = (22/15) * (25/2) km = 275/3 km

Answer

The distance walked by the tourist is 176/3 km, and the distance ridden on the bicycle is 275/3 km. Therefore, the distance ridden on the bicycle is greater by 99/3 km.

Note: The answer has been calculated using the given information and mathematical calculations.
