Two ants race across a table 63 cm long. One
travels at 5.14 cm/s and the other at 3 cm/s.
When the first one crosses the finish line,
how far behind is the second one?
Answer in units of cm
To find how far the second ant is behind the first ant when the first ant crosses the finish line, we need to calculate the time it takes for the first ant to complete the race.
We know that the table is 63 cm long and the first ant is traveling at a speed of 5.14 cm/s. We can use the formula:
Time = Distance / Speed
Time = 63 cm / 5.14 cm/s
Calculating this:
Time = 12.224 seconds (rounded to 3 decimal places)
Now, we can calculate the distance the second ant travels in the same amount of time.
Distance = Speed * Time
Distance = 3 cm/s * 12.224 seconds
Calculating this:
Distance = 36.672 cm (rounded to 3 decimal places)
Therefore, when the first ant crosses the finish line, the second ant is approximately 36.672 cm behind.
