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.

Street lenght = 600m.
Time is taken by the person to Cross the street = 5min,
600m/5min *(3/50) = 7.2km/hr,
Speed of the person in km =7.2km/hr.
1m/min = 3/50km/hr.
Time is taken by the person to Cross the street = 5min,
600m/5min *(3/50) = 7.2km/hr,
Speed of the person in km =7.2km/hr.
1m/min = 3/50km/hr.

Its simple, no need to go through 18/5. do one thing,
1st convert m/s into km/hr i.e. (2m/s=2*3600/(1000)) after doing this calculation you will get {7.2 km/hr}
1st convert m/s into km/hr i.e. (2m/s=2*3600/(1000)) after doing this calculation you will get {7.2 km/hr}

Given that,
Distance(d) = 600 m = 600/1000 km = 0.6 km.
Time(t) = 5 mns = 5/60 hrs = 1/12 hrs.
Now speed = distance/time = 0.6/(1/12) kmph = 0.6*12 = 7.2 kmph.
Distance(d) = 600 m = 600/1000 km = 0.6 km.
Time(t) = 5 mns = 5/60 hrs = 1/12 hrs.
Now speed = distance/time = 0.6/(1/12) kmph = 0.6*12 = 7.2 kmph.

And onething before attempting the answers. We should study the formulas. Hence it is given in Important formulas. We must calculate using by mentioned formulas.

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.

Distance= 600m
= 0.6km
Time = 5mins.
=5/60hrs.
Speed = D/T.
= 0.6/0.08333.
= 7.2km/hr.
So, Speed = 7.2km/hr.
= 0.6km
Time = 5mins.
=5/60hrs.
Speed = D/T.
= 0.6/0.08333.
= 7.2km/hr.
So, Speed = 7.2km/hr.

In 5 minutes the person crosses 600 meter.
In 1 minute the person crosses 600/5 meter.
In 60 minutes the person crosses (600*60)/5 = 7200 meter = 7.2 km.
In 1 minute the person crosses 600/5 meter.
In 60 minutes the person crosses (600*60)/5 = 7200 meter = 7.2 km.

Time = 5 min.
Distance = 600 meter.
Distance = 600/5 = 120m in one minute.
In hour = 120x60 = 7200m in one hour.
1km = 1000m.
7200m = 7.2m=>answer.
Distance = 600 meter.
Distance = 600/5 = 120m in one minute.
In hour = 120x60 = 7200m in one hour.
1km = 1000m.
7200m = 7.2m=>answer.

600 mtr in 5 minutes so
1 km = 1000 mtr
(600/5=120 mtrs per minute) so
1 hour = 60 minutes so
(60*120=7200 mtrs)
Here
(7200/1000)= 7.2 km/hr.
1 km = 1000 mtr
(600/5=120 mtrs per minute) so
1 hour = 60 minutes so
(60*120=7200 mtrs)
Here
(7200/1000)= 7.2 km/hr.
