Question

an old man walks 1km 20m in 20min.find it's speed in km/h​

Answer 1

Step-by-step explanation:

distance traveled by old man = 1Km 20M

1Km=1000m

so,1M= 0.001×20=0.02Km

speed = D÷t

= 0.02/20/60=0.06kmph

so the old mans speed is 0.06kmph

Answer 2

Answer:

Distance:- 1km 20min

= 1.02km

Time:- 20min

=1/3hr

Then,

Speed :- D/T

= 1.02 * 1/3

=3.06 km/hr
