The cyclist and the driver went in opposite directions. The speed of the cyclist is 15 km / h and the driver’s speed is three times higher. After what time the distance between them becomes 120 km.
1. Let’s calculate at what speed the driver was driving per hour, if it is known that his speed was 3 times the speed of the cyclist.
15 * 3 = 45 kilometers.
2. Determine how many kilometers per hour they moved away from each other.
45 + 15 = 60 kilometers.
3. Find after what time the distance between them becomes 120 kilometers.
120/60 = 2 hours.
Answer: In two hours the distance between the cyclist and the driver will be 120 kilometers.
