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.

s = d/t.
600/300 m/sec,
= 2 m/sec.
2 * 18/5 km/hr.
s = 36/5 kmph.
600/300 m/sec,
= 2 m/sec.
2 * 18/5 km/hr.
s = 36/5 kmph.

s = d/t.
d = 600m,
t = 5min,
s = 600/5 * 60,
= 2 m/sec.
2 * 18/5.
= 7.2.
d = 600m,
t = 5min,
s = 600/5 * 60,
= 2 m/sec.
2 * 18/5.
= 7.2.

Speed = 600 m/sec.
=> 600/ 5 x 60,
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
2 multiply 3600/1000,
= 18 km/hr.
Then
= 2 x18/5 km/hr
= 7.2 km/hr.
=> 600/ 5 x 60,
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
2 multiply 3600/1000,
= 18 km/hr.
Then
= 2 x18/5 km/hr
= 7.2 km/hr.

Speed = dis/time.
Dis = 600.
Speed = (600÷5*60) = 2m/sec.
We need speed km/hr 18/5.
2*18÷5 = 7.2km/hr.
Dis = 600.
Speed = (600÷5*60) = 2m/sec.
We need speed km/hr 18/5.
2*18÷5 = 7.2km/hr.
