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.

We know that speed=(distance / time).
so speed=(600/300)=2m/s.
2m/s= 2(18/5)=7.2km/hr.
so speed=(600/300)=2m/s.
2m/s= 2(18/5)=7.2km/hr.

1km/hr=(1ooo/3600)m/s=(5/18)m/s
for converting m/s into km/hr 18/5 is required to use
for converting m/s into km/hr 18/5 is required to use

It was a format when converted to m/s to km /hr use 18/5 and Km/hr to m/s use 5/18.

When we convert km/hr to m/s it's 18/5 and when we convert m/s to km/he it's 5/18.

2*60(min)*60(hr)/1000.
Then we get the answer 36/10(or)18/5*2.
Answer=7.2km/hr.
Then we get the answer 36/10(or)18/5*2.
Answer=7.2km/hr.

Its just a one step answer. Just calculate how much he can travel in 60 minutes.

What's that conversion formula come from the real real formula was 1000/(60*60)?

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