The bus travels at a speed of 40 km / h. Will it manage to cover 5 km in 15 minutes if it moves at the same speed?

Let’s determine what part of an hour represents a time interval of fifteen minutes:
15: 60 = 1/4 = 0.25.
Let us calculate how many kilometers the distance that the specified bus will cover in fifteen minutes will equal, if it is known, based on the data from the conditions of this task, that its speed will be constant and equal to 40 km / h:
40 * 0.25 = 10.
Let’s determine whether he can travel a distance of five kilometers in fifteen minutes by comparing the values:
5 <10.
Answer: Yes, he will be able to pass.
