Question

Which is greater: a speed of 45 km/h or a speed of 12.25 m/sec?
How much is the distance travelled for each of the values of speed given above in 2 seconds?

Answer 1

Answer:

Convert km/h to m/s;

45*5/18 m/s=12.5m/s

Since ;

0.5>0.25

hence,

45km/h>12.25m/s

Distance for 45 km/h(12.25m/s)

=12.5/2m

=6.25m

Distance for 12.25m/s

=6.125m
