which ant will reach the edge first?
Answer to Problem 9E
Ant B will reach the edge of the table first
Explanation of Solution
Given information: Ant A travels at a speed of
Formula used: consider the formula provided in the question,
Distance = speed × time
Calculation:
For ant A,
Distance =
Rate =
Let x be the time taken to reach the edge,
Substitute the values in the formula provided,
Multiply the multiplicative inverse of
Time taken by Ant A to reach the edge is 14 seconds.
For ant B,
Distance =
Speed =
Let x be the time taken to reach the edge,
Multiply the multiplicative inverse of
Time taken by ant B is 13 seconds.
Compare the time taken by ant A and ant B,
14 > 13
The time taken by Ant B is less.
Hence, ant B will reach the edge of the table first.
