A car is traveling at a speed of 81 kilometers per hour. What is the car's speed in meters per second? How many meters will the
car travel in 20 seconds? Do not round your answers.
1 answer:
Answer:
450meters
Step-by-step explanation:
Given data
Speed = 81km per hour
Let us convert to meter per seconds
1 km= 1000m
1 hour=3600 seconds
= 1000/3600= 5/18 m/s
=81*5/18
=405/18
=22.5 m/s
Hence the distance traveled in 20 seconds is
distance= speed*time
distance= 22.5*20
distance= 450 meters
Hence the distance is 450meters
