Question

Туристу нужно добраться до туристической базы , расстояние до которой 60 км. сначала он ехал 2 ч на велосипеде со скоростью 16 км/ ч, а потом 3 ч ушёл пешком со скоростью 4 км/ч и после этого сделал привал . сколько километров ему осталось пройти?(задачу решить выражением .)

Answer 1

16*2=36 км
3*4=12 км
12+36=48 км
60-48=12 километров осталось пройти

Answer 2

Problem Analysis

A tourist needs to reach a tourist base that is 60 km away. The tourist first travels on a bicycle for 2 hours at a speed of 16 km/h and then walks for 3 hours at a speed of 4 km/h. After that, the tourist takes a break. We need to determine how many kilometers the tourist has left to travel.

Solution

To solve this problem, we need to calculate the total distance covered by the tourist and subtract it from the total distance to the tourist base.

Let's calculate the distance covered by the tourist on the bicycle: Distance = Speed × Time Distance = 16 km/h × 2 h Distance = 32 km

Next, let's calculate the distance covered by the tourist on foot: Distance = Speed × Time Distance = 4 km/h × 3 h Distance = 12 km

Now, let's calculate the total distance covered by the tourist: Total Distance = Distance on Bicycle + Distance on Foot Total Distance = 32 km + 12 km Total Distance = 44 km

Finally, let's calculate the distance remaining for the tourist to reach the tourist base: Distance Remaining = Total Distance to Tourist Base - Total Distance Covered Distance Remaining = 60 km - 44 km Distance Remaining = 16 km

Therefore, the tourist has 16 km left to travel to reach the tourist base.

Answer

The tourist has 16 kilometers left to travel to reach the tourist base.
