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.

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.

Here, the formula is either:
Sspeed= distance divided by time.
Time = distance divided by speed.
or
Distance = speed x time.
Sspeed= distance divided by time.
Time = distance divided by speed.
or
Distance = speed x time.

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.
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.

600m = 5 minutes, 120m = 1 minutes (600/5),
1 hour = 60 minutes,
7200m = 60 minutes (120*60),
1000m = 1 km.
7200m = 7.2 km.
1 hour = 60 minutes,
7200m = 60 minutes (120*60),
1000m = 1 km.
7200m = 7.2 km.

Speed = Distance/Time.
Distance = 600 m = 600/1000 = 0.6 km
Time = 5 min = 5/60 = 0.083 min.
Speed = 0.6/0.083 = 7.2 km/hr.
Distance = 600 m = 600/1000 = 0.6 km
Time = 5 min = 5/60 = 0.083 min.
Speed = 0.6/0.083 = 7.2 km/hr.

1000 m = 1 km.
60 min = 1 hr,
In, 60 min × 600 m = 36000 m.
36000 m = 36 km.
Now, 36 (km) ÷ 5 (min) = 7.2.
So, 7.2 Km/hr.
60 min = 1 hr,
In, 60 min × 600 m = 36000 m.
36000 m = 36 km.
Now, 36 (km) ÷ 5 (min) = 7.2.
So, 7.2 Km/hr.

Hi @Sundar.
Your explanation is very nice. Can you tell me basic math's tricks like Percentage. How to calculate it is?

The formula of converting into m/s an km/hr is;
m/s: XYZ multiplied by 18 by 5.
And
km/hr: XYZ multiplied by 5 by 18.
m/s: XYZ multiplied by 18 by 5.
And
km/hr: XYZ multiplied by 5 by 18.

D = S*T.
D = 600m,
T = 5 mints => 5 * 60 = 300 sec.
S = D/T = 600/300 = 2 m/sec.
convert m/sec to km/hr,
2*18/5 = 7.5.
D = 600m,
T = 5 mints => 5 * 60 = 300 sec.
S = D/T = 600/300 = 2 m/sec.
convert m/sec to km/hr,
2*18/5 = 7.5.
