1.
A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?
Answer: Option
Explanation:
| Speed = |  |
600 |  m/sec. |
| 5 x 60 |
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
| = | |
2 x | 18 | |
km/hr |
| 5 |
= 7.2 km/hr.

Just formula s=d/t
=600/5*60m/sec
=600/5*60m/sec

s=d/t
=600/5*60
=600/300
=2m/s
1km=1000m
1/1000km=1m
3600s=1hr
1/3600=1s
2*3600/1000=7.2km/hr
=600/5*60
=600/300
=2m/s
1km=1000m
1/1000km=1m
3600s=1hr
1/3600=1s
2*3600/1000=7.2km/hr

T=5 Min, 5*60=300sec
SPEED=DISTANCE/TIME
=600/300
=2m/s
convert m/s to km/sec by formula
2*18/5
=36/5
=7.2km/hr
SPEED=DISTANCE/TIME
=600/300
=2m/s
convert m/s to km/sec by formula
2*18/5
=36/5
=7.2km/hr

For 600m 5 min. thn for
60min .... km
=> 600/5*60= 2m/sec
convert to km
so for 1 hr 3600sec
and 1000m = 1km
3600*2/1000=7.2km
60min .... km
=> 600/5*60= 2m/sec
convert to km
so for 1 hr 3600sec
and 1000m = 1km
3600*2/1000=7.2km

speed=distance/time
so the given distance is 600m and time is 5 mins..for this we have to convert minutes into seconds..5*60=300 seconds.
speed=(600*300)m/sec=2m/sec bt in answer they given in km/hr so we have to change m/sec in km/hr
speed=(2*18/5)km/hr=7.2 km
