Question

A car is traveling at a rate of 10 meters per second in a 20–mile–per–hour speed limit zone. Note: 1 mile is approximately 1.60934 kilometers. Which of the following statements are true? Select all that apply.

A The car is traveling at a speed of 0.001 km per second.
B The car is traveling at a speed of 0.6 km per minute.
C The car is traveling at a speed of 36 km per hour.
D The car is traveling at a speed of about 57.9 mph.
E The car is traveling within the speed limit.
F The car is traveling over the speed limit.

Answer 1

To convert from meters per second to kilometers per hour, the car is traveling at a speed of 0.6 km per minute, 36 km per hour, and about 57.9 mph.

Step-by-step explanation:

To convert from meters per second to kilometers per hour, we can use the conversion factor of 3.6 (since 1.0 m/s = 3.6 km/h).

1. The car is traveling at a speed of 0.6 km per minute (10 m/s x 3.6 km/h).

2. The car is traveling at a speed of 36 km per hour (10 m/s x 3.6 km/h).

3. The car is traveling at a speed of about 57.9 mph (10 m/s x 3.6 km/h x 0.621371 mi/km).

Therefore, the correct statements are:

• The car is traveling at a speed of 0.6 km per minute.
• The car is traveling at a speed of 36 km per hour.
• The car is traveling at a speed of about 57.9 mph.
