Question

Лодка проплыла 1 км со скоростью 100 м/мин. За это же время пловец проплыл 400м . С какой скоростью ехали туристы?Туристы выехали на лошадях с турбазы в 10 часов и остановились на привал в 13 часов. До привала они преодолели 39 км. С какой скоростью ехали туристы?

Answer 1

1) 13-10=3(ч) проехали туристы
2)39/3=13(км/ч) скорость

Answer 2

1км=1000м
1)1000:100=10мин-время в пути.
2)400:10=40м\мин-скорость пловца.

Answer 3

Calculation of Boat Speed:

To determine the speed at which the tourists were traveling, we need to calculate the speed of the boat first. We are given that the boat traveled 1 km with a speed of 100 m/min.

To find the time it took for the boat to travel 1 km, we can use the formula:

Time = Distance / Speed

Substituting the given values, we have:

Time = 1 km / 100 m/min

Converting 1 km to meters (1 km = 1000 m), we get:

Time = 1000 m / 100 m/min

Simplifying the expression, we find:

Time = 10 min

Therefore, it took the boat 10 minutes to travel 1 km.

Calculation of Swimmer's Speed:

Next, we are given that the swimmer traveled 400 m in the same amount of time it took the boat to travel 1 km (10 minutes).

To calculate the swimmer's speed, we can use the formula:

Speed = Distance / Time

Substituting the given values, we have:

Speed = 400 m / 10 min

Simplifying the expression, we find:

Speed = 40 m/min

Therefore, the swimmer's speed was 40 m/min.

Calculation of Tourists' Speed:

Now, let's calculate the speed at which the tourists were traveling. We are given that the tourists traveled 39 km from the tourist base to the resting place in a time span of 3 hours (from 10 am to 1 pm).

To find the speed, we can use the formula:

Speed = Distance / Time

Substituting the given values, we have:

Speed = 39 km / 3 hours

Converting 39 km to meters (1 km = 1000 m), we get:

Speed = 39,000 m / 3 hours

Converting hours to minutes (1 hour = 60 minutes), we have:

Speed = 39,000 m / 180 minutes

Simplifying the expression, we find:

Speed ≈ 216.67 m/min

Therefore, the speed at which the tourists were traveling was approximately 216.67 m/min.

Please note that the given search snippet does not provide direct information about the speed of the tourists. However, we can calculate it based on the given distance and time.
