At the school track meet, Dita ran 100 meters at a rate of 6.25 meters per second.

Question

time = distance/rate
t = d/r

How long did it take Dita to finish the race?

A. 16 seconds
B. 625 seconds
C. 106.25 seconds
D. 93.75 seconds

Answer 1

To find out how long it took Dita to finish the race, we can use the formula:

\[ t = \frac{d}{r} \]

where:

• \( d \) is the distance (100 meters),
• \( r \) is the rate (6.25 meters per second).

Substituting the values:

\[ t = \frac{100 \text{ meters}}{6.25 \text{ meters/second}} \]

Calculating this gives:

\[ t = \frac{100}{6.25} = 16 \text{ seconds} \]

Therefore, the time it took Dita to finish the race is A. 16 seconds.
