From two cities, the distance between which is 5 kilometers, two motorists simultaneously drove towards each other and after 2 hours they met The speed of one of the motorists is 2 kilometers per hour Find the speed of the first motorist
Let’s find how much the second motorist traveled in 2 hours, who was driving at a speed of 2 km / h. To do this, multiply the speed of the motorist by the travel time:
2 * 2 = 4.
We know the distance between the two cities and we know that one of the motorists drove 4 km before the meeting. Let’s find how much another motorist has driven:
5 – 4 = 1.
Now we know that before the meeting the first motorist drove 1 km and the time during which he covered this path. Let’s find the speed with which he was traveling:
1/2 = 0.5 km / h.
Answer: the speed of the first motorist was 0.5 km / h.
