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.

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.

600/5 = 120.
120m per minute.
120 * 60min = 7200m.
1000m = 1 km.
7200/1000 = 7.2km per hour.
120m per minute.
120 * 60min = 7200m.
1000m = 1 km.
7200/1000 = 7.2km per hour.

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.

1km = 1000m.
7200m = 7.2m=>answer.

600/5=120m
60*120=7200
7.2km.
Correct me, If I am wrong.
60*120=7200
7.2km.
Correct me, If I am wrong.

Distance = 600m = 600/1000 km
= 0.6 km.
Time = 5mint = 5/60 hr = 1/12 hr.
Speed = Distance/time.
= (0.6)/1/12.
= 0.6×12.
=7.2
= 0.6 km.
Time = 5mint = 5/60 hr = 1/12 hr.
Speed = Distance/time.
= (0.6)/1/12.
= 0.6×12.
=7.2

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.

We know,
1 min = 60 sec.
5 min = 60 * 5 = 300 sec.
A/c to question;
Distance = 600 m.
Time = 300 Sec.
Now speed = Distance/ Time = 600/ 300 = 2 m/s.
Converting km to meter, multiply with 18/5.
Now, 2*18/5 = 36/5 = 7.2 km/hr.
1 min = 60 sec.
5 min = 60 * 5 = 300 sec.

S = d/t.
600m = 0.6km.
5minutes = 5/60 = 0.083hr,
S = 0.6/0.083,
= 7.2km/hr.
600m = 0.6km.
5minutes = 5/60 = 0.083hr,
S = 0.6/0.083,
= 7.2km/hr.

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.
