Let x km/h be the Jim's speed. If the difference in Jim's and John's speeds is 2 km/h, then the John's speed is x+2 km/h.
1. John takes 15 minutes to walk with speed x+2 km/h from school to the bus station, then the distance is 15·(x+2) km.
2. Jim takes 20 minutes to walk with speed x km/h from school to the bus station, then the distance is 20·x km.
3. The distance is the same, so
20x=15(x+2),
20x=15x+30,
20x-15x=30,
5x=30,
x=30:5,
x=6.
Answer: the distance between the station and the school is 6 km.
Answer:
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression.
Step-by-step explanation:
13 is prime, so 13/75 can't be reduced. You could, however,
write
13/75 = 0.17333... This is a repeating decimal.
Well you didn't give me a sentence, but if you'd like to find out how to get the answer, just find the least common multiple of the words, meaning however many letters there are in a word count those, do that for the whole sentence and you get your answer.
