Final answer:
To determine the distance a garbage truck will travel in 0.4 hour at 1.87 km/h, multiply the speed by the time, which results in 0.748 kilometers.
Step-by-step explanation:
If a garbage truck travels at a speed of 1.87 km per hour (kph), then to find out how many kilometers it will travel in 0.4 hour, you simply multiply the speed by the time. So, you calculate it as follows:
Distance = Speed × Time
Distance = 1.87 kph × 0.4 hour
Distance = 0.748 km
Therefore, the garbage truck will travel 0.748 kilometers in 0.4 hour.
