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.

@Kishor Venkkat.
It is based on m.k.s system of units.
m.k.s= metre.kilogram.second.
So, as given in minutes, we have to convert it into seconds.

Here is a simple solution guys.
distance - 600,
mins - 5,
600/5 = 120 speed.
120 * 60 seconds = 7200 meters/1000 meters.
= 7.2 km Result.

120 * 60 seconds = 7200 meters/1000 meters.
= 7.2 km Result.

Simply,
(2/1000) = 0.002km/sec
Then (0.002*3600) = 7.2km/sec.
Note: small quantity to big quantity then divide i.e; 2/1000 = meter into kms.
(2/1000) = 0.002km/sec
Then (0.002*3600) = 7.2km/sec.

Speed = dis/time so speed = 600/5 convert it directly to km/hr (1 km= 1000m and1 hour = 60 minutes).
So, speed = 600*60/5*1000 = 7.2km/hr.
So, speed = 600*60/5*1000 = 7.2km/hr.

Formula: speed = distance/time.
In question, given distance is in meter so convert the km and time given the minute so convert hours.

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.
600m Distance.
Time 5 Minute = 300 Seconds.

T=5 Min, 5*60=300sec
SPEED=DISTANCE/TIME
=600/300
=2m/s
convert m/s to km/sec by formula
2*18/5
=36/5
=7.2km/hr
SPEED=DISTANCE/TIME
=600/300
=2m/s
convert m/s to km/sec by formula
2*18/5
=36/5
=7.2km/hr

Very simple,
In 5 mins he covers 600 m.
In 1 min he will cover 600/5.
In 60 mins he will cover (600*60) /5 = 7200 m i.e. 7. 2 km.
In 5 mins he covers 600 m.
In 1 min he will cover 600/5.
In 60 mins he will cover (600*60) /5 = 7200 m i.e. 7. 2 km.
