1.
A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?
3.6
7.2
8.4
10
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.

1000m = 1 km.
So, 1 m =( 1/1000) km,
600 m = 600/1000, i.e 0.6 km,
In 5 minutes a person passes 0.6km,
In 1 minute a person passes 0.6/5,
In 60 minutes a person passes (0.6x60)/5, i.e 7.2 km.

Ans : 7.2 km.

600 meters in 300 seconds;
100 meters in 50 seconds;
1000 meters in 500 seconds (8,33 minutes):
60 divided by 8,33 = 7,4 kmh.

How that 18 came?

Mallikarjun said:   2 decades ago
1km/hr=(1ooo/3600)m/s=(5/18)m/s
for converting m/s into km/hr 18/5 is required to use
