A car is driving at 90 kilometers per hour. How far, in meters, does it travel in 5 seconds?

 meters

Give your answer to the nearest meter.

To determine how far the car travels in 5 seconds, we'll need to use the relationship between speed, time, and distance.

### 1. Convert the Speed to Meters per Second
The speed of the car is given in kilometers per hour (km/h). First, we'll convert this to meters per second (m/s).

\[
1 \text{ kilometer} = 1000 \text{ meters}
\]
\[
1 \text{ hour} = 3600 \text{ seconds}
\]

So, the conversion factor from km/h to m/s is:

\[
1 \text{ km/h} = \frac{1000 \text{ meters}}{3600 \text{ seconds}} = \frac{5}{18} \text{ m/s}
\]

Now, convert 90 km/h to m/s:

\[
90 \text{ km/h} \times \frac{5}{18} = 25 \text{ m/s}
\]

### 2. Calculate the Distance Traveled in 5 Seconds
Using the formula for distance:

\[
\text{Distance} = \text{Speed} \times \text{Time}
\]

\[
\text{Distance} = 25 \text{ m/s} \times 5 \text{ seconds} = 125 \text{ meters}
\]

### Final Answer:

The car travels **125 meters** in 5 seconds.
