Answer 1

1)12+40=52 скорость сближения мотоциклистов                                                     2) 52*2=104 км (на 104 км приблизятся через 2 часа

Answer 2

Speed of Approach:

The speed of approach of the bicyclist and the motorcyclist can be found by adding their speeds together. The bicyclist's speed is 12 km/h, and the motorcyclist's speed is 40 km/h. Therefore, the speed of their approach is 12 km/h + 40 km/h = 52 km/h.

Distance Covered in 2 Hours:

To find out how far the bicyclist and the motorcyclist will have approached each other in 2 hours, we can use the formula: distance = speed * time. - For the bicyclist: distance = 12 km/h * 2 h = 24 km - For the motorcyclist: distance = 40 km/h * 2 h = 80 km

So, the total distance covered by both in 2 hours is 24 km + 80 km = 104 km. Therefore, the bicyclist and the motorcyclist will have approached each other by 104 kilometers after 2 hours
