48 км : 1ч 40 мин=??км/ч48км : 1ч 20 мин=??км/ч48 км:1 ч 15 мин=??​км/ч

Answer 1

Ответ:

28.8 км/ч

36 км/ч

38.4 км/ч

Answer 2

To calculate the speed in km/h (kilometers per hour), you can use the formula:

Speed (km/h) = Distance (km) / Time (hours)

Let's calculate the speeds for each given scenario:

1. 48 km in 1 hour 40 minutes: Time = 1 hour + 40 minutes = 1.6667 hours (approx) Speed = 48 km / 1.6667 hours ≈ 28.8 km/h

2. 48 km in 1 hour 20 minutes: Time = 1 hour + 20 minutes = 1.3333 hours (approx) Speed = 48 km / 1.3333 hours ≈ 36 km/h

3. 48 km in 1 hour 15 minutes: Time = 1 hour + 15 minutes = 1.25 hours Speed = 48 km / 1.25 hours = 38.4 km/h

So, the speeds for each scenario are approximately:

1. 28.8 km/h
2. 36 km/h
3. 38.4 km/h
