Question

In a relay race, the total distance to be covered is 1 ½ km. Each runner on the team is required to run ¼ of a km. How many runners are needed for a team?

A) 3 runners
B) 4 runners
C) 5 runners
D) 6 runners

Answer 1

The question requires finding the number of runners required for a relay race given the total distance and each runner's distance. This is done by dividing the total distance by the distance each runner will cover. The answer is 6 runners.

Step-by-step explanation:

The subject of this question is Mathematics and it's a middle school level problem. The question is asking to figure out how many runners are needed for a team in a relay race if the total distance to be covered is 1 ½ km and each runner is required to run ¼ km. To solve this, we divide the total distance by the distance each runner will cover. That is, 1 1/2 km divided by 1/4 km.

When we convert 1 1/2 to an improper fraction, we have 3/2. So, our calculation becomes (3/2) divided by (1/4). To divide by a fraction, we multiply by its reciprocal. The reciprocal of 1/4 is 4/1. So, (3/2) multiplied by (4/1) equals 6.

The answer is therefore (D) 6 runners.
