You are given a car that travels
at 150 kilometers in 7200 seconds. You are required to find the speed of the
car. Keep in mind that the equation for speed is distance over time. Let us
denote s for speed, d for distance and t for time. So,
s = d/t
s = 150km/7200s
s = 1/48 or 0.020833 km/s
We can convert the kilometers
into meters. 1km=1000m. so,
0.020833km/s (1000m/1km) = 20.83
m/s
The car travels with a speed of 0.020833 km/s or 20.83 m/s.
