The distance between the two motorcyclists at the beginning of their simultaneous movement towards each other was equal to 220 km. After what time it will be equal to 40 km., If the speed of one motorcyclist is known to be 60 km / h and it is twice the speed of another.

1. Let us find the speed of the second cyclist if it is known that his speed is 2 times less than the speed of the first cyclist.
60/2 = 30 kilometers per hour.
2. Find out the speed of convergence per hour for both cyclists.
60 + 30 = 90 kilometers.
3. Let’s find what distance they have to travel so that the distance remains 40 kilometers between them.
220 – 40 = 180 kilometers.
4. Let’s calculate after what time the distance between motorcyclists will be equal to 40 kilometers.
180/90 = 2 hours.
Answer: In two hours the distance between the riders will be 40 kilometers.
