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.

Given:
Distance = 600 m
Time = 5 minutes.
So, find speed
Formula: speed = Distance/Time.
Apply =>speed = 600m/5 minutes.
=120 meters per minute.
(Answer: 120 meters per minute, So find for 1 hour i.e 1 hour = 60 minutes)
Then,
60 minutes x 120 meters = 7200m.
We know 1000 meters = 1 km.
So,
7000 meters = 7 km.
Extra 200 meters = 0.2
=> 7 km + 0.2 km = 7.2 km.
Distance = 600 m
Time = 5 minutes.
So, find speed
Formula: speed = Distance/Time.
Apply =>speed = 600m/5 minutes.
=120 meters per minute.
(Answer: 120 meters per minute, So find for 1 hour i.e 1 hour = 60 minutes)
Then,
60 minutes x 120 meters = 7200m.
We know 1000 meters = 1 km.
So,
7000 meters = 7 km.
Extra 200 meters = 0.2
=> 7 km + 0.2 km = 7.2 km.

600 meters in 5 minutes.
To find 1 min distance;
= 600/5
= 120 meters in 1 min
60 min in 1 hour.
Multiply by 60 min to find the total distance in meters in 1 hour.
= 120 * 60.
= 7200 meter.
Convert into kilometre multiplied by 1000;
7200/1000.
7.2 kilometers in 1 hour.
To find 1 min distance;
= 600/5
= 120 meters in 1 min
60 min in 1 hour.
Multiply by 60 min to find the total distance in meters in 1 hour.
= 120 * 60.
= 7200 meter.
Convert into kilometre multiplied by 1000;
7200/1000.
7.2 kilometers in 1 hour.

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

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.

18/5 is a formula that's used to convert m\s to k/hour.

Speed = 600 m/sec.
=> 600/ 5 x 60,
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
2 multiply 3600/1000,
= 18 km/hr.
Then
= 2 x18/5 km/hr
= 7.2 km/hr.
=> 600/ 5 x 60,
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
2 multiply 3600/1000,
= 18 km/hr.
Then
= 2 x18/5 km/hr
= 7.2 km/hr.

600/5 = 120.
120m per minute.
120 * 60min = 7200m.
1000m = 1 km.
7200/1000 = 7.2km per hour.
120m per minute.
120 * 60min = 7200m.
1000m = 1 km.
7200/1000 = 7.2km per hour.

Distance = 600m = 600/1000 km
= 0.6 km.
Time = 5mint = 5/60 hr = 1/12 hr.
Speed = Distance/time.
= (0.6)/1/12.
= 0.6×12.
=7.2
= 0.6 km.
Time = 5mint = 5/60 hr = 1/12 hr.
Speed = Distance/time.
= (0.6)/1/12.
= 0.6×12.
=7.2
