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.

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.

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.

Distance = 600m = 0.6 km.
Time=5 mins= 5/60 hours.
Speed = distance/time = (0.6*60)/5 km/hr.
Speed= 7.2 km/hr.
Time=5 mins= 5/60 hours.
Speed = distance/time = (0.6*60)/5 km/hr.
Speed= 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.

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.

@Vijaya Lakshmi.
it is how we get 18/5.
1 km = 1000m.
1 km/h = 1000m/h.
= 1000/60 m/min.
= 1000/(60*60) m/s.
= 1000/3600m/s.
= 5/18 m/s.
Similarly,
1 m/s = 18/5 km/h.
it is how we get 18/5.
1 km = 1000m.
1 km/h = 1000m/h.
= 1000/60 m/min.
= 1000/(60*60) m/s.
= 1000/3600m/s.
= 5/18 m/s.
Similarly,
1 m/s = 18/5 km/h.

Km defines distance.
Hr defines time.
Question is to find speed?
S = km/hr.
1. To find m to km.
1 Meter to 1000km.
600Meter is 600/1000 = 0.6km.
2. To find min to hr.
60 min =1hr.
5/60 = 0.08hr.
Finally.
S = KM/hr
= 0.6/0.08
= 7.5km/hr.
Hr defines time.
