Question

The average speed of a bicycle, an athlete and a car are 18km/hr,7m/s and 2km/min respectively. Which of the three is the fastest and which is the slowest?

Answer 1

hey dear here is your answer
average speed of bicycle is 18km/h , let us concert convert it into m/s
=18×5/18 m/s
=5 m/s

now average speed of athlete is 7 m/s , we don't need to convert since it is already in m/s

now average speed of a car is 2 km/min let us convert it into m/s
so, 1km = 1000m
2km= (2×1000)m
= 2000m
1 min =60 s
so, 2000/60
=33.3 m/s
hence, the car travels faster and the bicycle travels the slowest.
hope it helps you. ..

Answer 2

Answer:

average speed of bicycle is 18km/h , let us concert convert it into m/s

=18×5/18 m/s

=5 m/s

now average speed of athlete is 7 m/s , we don't need to convert since it is already in m/s

now average speed of a car is 2 km/min let us convert it into m/s

so, 1km = 1000m

2km= (2×1000)m

= 2000m

1 min =60 s

so, 2000/60

=33.3 m/s

hence, the car travels faster and the bicycle travels the slowest.
