Question

for 25 points easist question Karen's dad's car, moving at a constant speed, covers 75 meters in 5 seconds. What is the car’s speed in km/hr? (1 km = 1000m)

Answer 1

1 hour = 3600 seconds.

3600 seconds / 5 seconds = 720

75 meters x 720 = 54,000 meters in one hour.

54,000 meters / 1000 = 54 km/hr.
