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.

1 hour 12 m - 5 = 60 minute = 1 HOUR,
Than 600 m - 12 = 7200 m
Now convert km/hour,
Than required answer 7200/1000 = 7.2 km/hour.
Than 600 m - 12 = 7200 m
Now convert km/hour,
Than required answer 7200/1000 = 7.2 km/hour.

1000 meter = 1 kilometer.
3600 seconds = 1 hour.
1000 meter/3600second=1 kilometer/1 hour.
5 meter/18 second = 1 kilometer/1 hour.
3600 seconds = 1 hour.
1000 meter/3600second=1 kilometer/1 hour.
5 meter/18 second = 1 kilometer/1 hour.

Speed = distance ÷ time.
= 600÷(5×60),
= 2 m/s.
Speed in km/hr:
= 2×(18/5),
= 7.2 km/hr.
= 600÷(5×60),
= 2 m/s.
Speed in km/hr:
= 2×(18/5),
= 7.2 km/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

We know that s=d/t,
d=600m and t=5m,
we know that,
1min.=60sec,
therefore, 5min=5*60=300sec,
600/300,
= 2.
2 * 18/5 = 7.2m/m.
d=600m and t=5m,

1min.=60sec,
therefore, 5min=5*60=300sec,
600/300,
= 2.
2 * 18/5 = 7.2m/m.

Why divided by 60?
If we want to convert minute to seconds then don't we have to multiply the minute * 60? Please anyone explain.

In 5 mins 600 meter.
In 1 mins 600/5 = 120 meter.
In 60 mins (1hr) 120*60 meter = 7200 meter.
In 1 hr 7.2 km.
i.e 7.2 km/hr.
In 1 mins 600/5 = 120 meter.
In 60 mins (1hr) 120*60 meter = 7200 meter.
In 1 hr 7.2 km.
i.e 7.2 km/hr.

t=5 Mins, 5*60=300sec(1min=60 sec)
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.

600 meters in 300 seconds;
100 meters in 50 seconds;
1000 meters in 500 seconds (8,33 minutes):
60 divided by 8,33 = 7,4 kmh.
100 meters in 50 seconds;
1000 meters in 500 seconds (8,33 minutes):
60 divided by 8,33 = 7,4 kmh.
