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.

Distance = 600m = 0.6 km.
Time=5 mins= 5/60 hours.
Speed = distance/time = (0.6*60)/5 km/hr.
Speed= 7.2 km/hr.
Time=5 mins= 5/60 hours.
Speed = distance/time = (0.6*60)/5 km/hr.
Speed= 7.2 km/hr.

Distance = 600 m = 0.6 km (since 1 km = 1000 m).
Time = 5 minutes = 5/60 hours (since 1 hour = 60 minutes).
Now we can use the formula:
Speed = Distance/Time.
Speed = 0.6 km / (5/60) hours
Speed = 0.6 km / 0.08333 hours.
Speed = 7.2 km/h
Therefore, the person's speed is 7.2 km/h (kilometres per hour).
Time = 5 minutes = 5/60 hours (since 1 hour = 60 minutes).
Now we can use the formula:
Speed = Distance/Time.
Speed = 0.6 km / (5/60) hours
Speed = 0.6 km / 0.08333 hours.
Speed = 7.2 km/h
Therefore, the person's speed is 7.2 km/h (kilometres per hour).

Speed = Distance/Time.
600m Distance.
Time 5 Minute = 300 Seconds.
We need speed km/hr, it means 18/5.
600/300*18/5 = 36/5.
Ans = 7.2.

The easiest way for solving this question is;
Divide distance by time: 600/5 = 120.
Then multiply 120 x 60 = 7200.
Then divide 7200 with 1000 meter = 7.2.
Divide distance by time: 600/5 = 120.
Then multiply 120 x 60 = 7200.
Then divide 7200 with 1000 meter = 7.2.

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.

Convert distance to kilo meters.
So, 600/1000 = 6/10.
And, convert minutes to hours.
So, 5/60.
6/10/5/60 = 36/5 answer is 7.2
So, 600/1000 = 6/10.
And, convert minutes to hours.
So, 5/60.
6/10/5/60 = 36/5 answer is 7.2

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.

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.
