Question

a car traveled 1025 km from El Paso to Dallas iin 13.5 hr. What was its average velocity

Answer 1

1) 1025km per 13.5hr = 1025km/13.5hr = 75.9 km/hr

2) 400km per 30min = 400km/30min = 13.3 km/min
13.3km/min X (60min per hr) = 13.3km/min(60min/hr) = 800km/hr

3) 45km/hr in 40min = 45km/hr X 40min X (1hr/60min) = 30km.

4) (30m/s - 10m/s) per 10s = 20m/s/10s = 2ms/s = 2m/s/s = 2m/s^2
