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.

Let's Convert distance metres to km;
600/1000 km = 0.6km.
Now, same as time, 5/60 = 1/12 hr.
Now speed = distance/time.
= 0.6/(1/12),
= 0.6 * 12,
= 7.2 km.
600/1000 km = 0.6km.
Now, same as time, 5/60 = 1/12 hr.
Now speed = distance/time.
= 0.6/(1/12),
= 0.6 * 12,
= 7.2 km.

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.

Speed = Distance ÷ time.
Speed = 600÷(5×60).
Speed = 2 m/sec,
Now, convert into kmph.
i.e.,S = 2×(18÷5).
Then S = 7.2 kmph.
Speed = 600÷(5×60).
Speed = 2 m/sec,
Now, convert into kmph.
i.e.,S = 2×(18÷5).
Then S = 7.2 kmph.
