Question

Помогите: турист шёл пешком 5 1/3 ч. со скоростью 4 1/8 км и ехал на велосипеде 1 7/15 ч. со скоростью 12 1/2 какое расстояние больше????? решите пж!!!!!!!!

Answer 1

1) 5 1/3*4 1/8=16/3*33/8=2*11=22 км. 2) 1 7/15*12 1/2=22/15*25/2=11/3*5=55/3=18 1/3 км. 3) 22 км больше, чем 18 1/3 км. Пешком расстояние больше.

Answer 2

Problem Statement

A tourist walked for 5 1/3 hours at a speed of 4 1/8 km/h and then rode a bicycle for 1 7/15 hours at a speed of 12 1/2 km/h. The question is, which distance is greater?

Solution

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

Similarly, to find the distance traveled by the tourist on the bicycle, we can multiply the time ridden by the speed: Distance ridden = Time ridden * Speed ridden

Let's calculate the distances:

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

To convert the mixed numbers to improper fractions, we can use the following conversions: 5 1/3 = (5 * 3 + 1) / 3 = 16/3 4 1/8 = (4 * 8 + 1) / 8 = 33/8

Distance walked = (16/3) * (33/8) km

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

To convert the mixed numbers to improper fractions, we can use the following conversions: 1 7/15 = (1 * 15 + 7) / 15 = 22/15 12 1/2 = (12 * 2 + 1) / 2 = 25/2

Distance ridden = (22/15) * (25/2) 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

To compare the distances, we can convert them to decimal form:

Distance walked = 176/3 km ≈ 58.67 km Distance ridden = 275/3 km ≈ 91.67 km

Therefore, the distance ridden on the bicycle is greater.

Please note that the calculations are approximate and rounded to two decimal places.

Answer

The distance ridden on the bicycle is greater than the distance walked.
