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.

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.

The formula of converting into m/s an km/hr is;
m/s: XYZ multiplied by 18 by 5.
And
km/hr: XYZ multiplied by 5 by 18.
m/s: XYZ multiplied by 18 by 5.
And
km/hr: XYZ multiplied by 5 by 18.

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.
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.

Answer: Option B.
Explanation:
Distance = 600 m.
Time = 5 min.
Speed = 600/5 = 120m/min or 120*60/1000 = 7.2km/hr.
Explanation:
Distance = 600 m.
Time = 5 min.
Speed = 600/5 = 120m/min or 120*60/1000 = 7.2km/hr.

Hi guys. I'm still confused. How did you compute 60x5/18 manually? How did you get the answer 50/8? Explain in detail.

Man crosses 600 meters in 5 minutes.
12 x 5 = 60 minutes => 1 hour,
So, 600 x 12 = 7200 meters/hr =>7.2 km/hr
12 x 5 = 60 minutes => 1 hour,
So, 600 x 12 = 7200 meters/hr =>7.2 km/hr

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

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.

Can someone explain where the 5 and 8 came from? I understand the formula but the 5 and 8 are throwing me off.
