Answer :

To solve this problem, we will calculate the distance traveled by the truck using the formula:

Distance = Speed × Time

Given:
- The speed of the truck is 15 meters per second (m/s).
- The time for which the truck travels is 20 minutes.

However, to use the formula correctly, we must ensure that the time is in the same units as the speed. Since the speed is given in meters per second (m/s), we need to convert the time from minutes to seconds.

There are 60 seconds in one minute. Therefore, to convert the time from minutes to seconds, we will multiply the number of minutes by 60.

Time in seconds (s) = Time in minutes × 60 seconds/minute
= 20 minutes × 60 seconds/minute
= 1200 seconds

Now that we have both the speed and time in compatible units, we can calculate the distance:

Distance = Speed × Time
= 15 m/s × 1200 s
= 18,000 meters

The truck travels a distance of 18,000 meters in 20 minutes at a speed of 15 m/s.
