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.

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

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.

Changing kmph to mps.
1km = 1000m.
Minute = 60sec.
1000/60×60 = 5/18.
Changing opposite mps to kmph is 18/5.
1km = 1000m.
Minute = 60sec.
1000/60×60 = 5/18.
Changing opposite mps to kmph is 18/5.

I will explain you in a simple way.
Distance/time into 3.6,
So, 600/300 * 3.6 = 7.2,
3.6 = 3600/1000.
Distance/time into 3.6,
So, 600/300 * 3.6 = 7.2,
3.6 = 3600/1000.

Speed = dis/time.
Dis = 600.
Speed = (600÷5*60) = 2m/sec.
We need speed km/hr 18/5.
2*18÷5 = 7.2km/hr.
Dis = 600.
Speed = (600÷5*60) = 2m/sec.
We need speed km/hr 18/5.
2*18÷5 = 7.2km/hr.

600m convert to KM = 600/1000 = 0.6,
5min convert to Hrs. = 5/60 = 0.083,
Finally, 0.6/0.083 = 7.22.
5min convert to Hrs. = 5/60 = 0.083,
Finally, 0.6/0.083 = 7.22.

Simple(no formulas).
600m/5 min = 120m per 1min.
1hr = 60min.
120x60 = 7200m .
7200m = 7.20km/hr.
600m/5 min = 120m per 1min.
1hr = 60min.
120x60 = 7200m .
7200m = 7.20km/hr.
