Answer:
0.1m/s
Step-by-step explanation:
Speed can be calculated using the formula;
Speed (m/s) = distance (m) รท time (s)
According to the information provided in this question, Alejandro's car travels 50cm in 5seconds i.e. the distance traveled is 50cm and the time is 5s.
However, the question requires the distance to be in metres (m). We, therefore, need to convert 50cm to m by dividing by 100.
100cm = 1m
50cm = 50/100
= 0.5metres.
Speed = 0.5/5
Speed = 0.1m/s.
The car travels as fast as 0.1m/s.
