Question

If a car travels 18,000 meters in 30 minutes, what is its average speed?

A) 1 m/s
B) 6 m/s
C) 10 m/s
D) 60 m/s

Answer 1

To find the average speed of a car that travels 18,000 meters in 30 minutes, convert the time to seconds (1800 s) and use the formula speed = distance / time, which results in an average speed of 10 m/s.

Step-by-step explanation:

To calculate the average speed of a car, we use the formula speed = distance / time. Given that a car travels 18,000 meters in 30 minutes, first we need to convert minutes into seconds to use the SI unit of time (1 minute = 60 seconds). Therefore, 30 minutes is 30 x 60 = 1800 seconds. Now we can calculate the average speed:

Speed = distance / time = 18,000 meters / 1800 seconds = 10 meters per second (m/s).

Thus, the correct answer is C) 10 m/s.
