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.

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.

Speed = Distance/Time.
Distance = 600 m = 600 *18/5 = 2160,
(We have to multiply distance * 18/5 to convert m to km)
Time = 5 mins = 5/60hrs,
(We have to divide mins by 60 to convert it to hr).
Now, Speed = 2160/5/60 = 2160/5(1/60) = 7.2,
Hope you understood now.
