Answer 1

60+70=130км/ч 390:130=3часа

Answer 2

1)60+70=130
2)390/130=3часа

Answer 3

Calculating the Meeting Time of Two Motorcyclists

To calculate the time it takes for two motorcyclists, traveling towards each other, to meet, we can use the formula:

Meeting time = Distance / (Speed of motorcyclist 1 + Speed of motorcyclist 2)

Given: - Distance between the two cities = 390 km - Speed of motorcyclist 1 = 60 km/h - Speed of motorcyclist 2 = 70 km/h

Using the above formula, we can calculate the meeting time.

Calculation

Meeting time = 390 km / (60 km/h + 70 km/h)

Meeting time = 390 km / 130 km/h

Meeting time ≈ 3 hours

Therefore, the two motorcyclists will meet after approximately 3 hours of traveling towards each other.
