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.

In 5min 600m,
In 1min, 600/5 = 120m,
In 1hr, 120 * 60 = 7200m,
1km = 1000m,
So, 7200m = 7.2km.
In 1min, 600/5 = 120m,
In 1hr, 120 * 60 = 7200m,
1km = 1000m,
So, 7200m = 7.2km.

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.

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.

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.

Let's Convert distance metres to km;
600/1000 km = 0.6km.
Now, same as time, 5/60 = 1/12 hr.
Now speed = distance/time.
= 0.6/(1/12),
= 0.6 * 12,
= 7.2 km.
600/1000 km = 0.6km.
Now, same as time, 5/60 = 1/12 hr.
Now speed = distance/time.
= 0.6/(1/12),
= 0.6 * 12,
= 7.2 km.

@All.
Here is my solution:
600m in 5 minutes.
1hr = 60 minutes,
5 รท 60 = 12,
12 x 600 = 7200.
Answer is 7.2 km/hr.
