If Mr. X can ride a bicycle 30 feet while Mr.Y runs 20 feet, how many feet can Mr.X ride
while Mr. Y runs 30 feet?
Since Mr. X can ride a bicycle 30 feet and Mr. Y runs 20 feet, we can assume they cover the same distance at the same time.
If Mr. X can ride a bicycle for 30 feet, we can write it as:
Mr. X (bicycle) = 30 feet
Let's find out how many feet Mr. Y can run while Mr. X rides the bicycle for 30 feet.
If the ratio of the distance Mr. X covers to that of Mr. Y is constant, we can write it as:
30 feet (Mr. X) / 20 feet (Mr. Y) = x feet (Mr. X) / 30 feet (Mr. Y)
Cross-multiplying, we get:
20 feet * x feet (Mr. X) = 30 feet * 30 feet (Mr. Y)
20x = 900
x = 900 / 20
x = 45
Therefore, Mr. X can ride a bicycle for 45 feet while Mr. Y runs for 30 feet.
