Question

compare the following speeds and arrange them in increasing order of their magnitude : a car running at 90 km/h, a bus moving at 20 m/s,a cycle covering 600 cm in 2 s

Answer 1

Answer:

speed of cycle < speed of bus < speed of train

Explanation:

speed of car = 90km/h

1km/h= 5/18 m/s

so, 90 km/h= 90*5/18 m/s

=25 m/s

speed of bus =20 m/s

Here,

distance covered= 600 cm

and 1cm =1/100 m

so, 600 cm= 600/100 m

=6 m

time taken= 2 s

speed of cycle =distance covered/ time taken

= 6/2 m/s

=3 m/s

Hence, speed of cycle(3 m/s) < speed of bus (20 m/s) < speed of train (25 m/s).
