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.

s = d/t.
d = 600m,
t = 5min,
s = 600/5 * 60,
= 2 m/sec.
2 * 18/5.
= 7.2.
d = 600m,
t = 5min,
s = 600/5 * 60,
= 2 m/sec.
2 * 18/5.
= 7.2.

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.

Simple way to solve this;
Distance = 600m = 600/1000 = 0.6Km.
Time = 5 minutes = 0.08 hours.
Speed = ?.
Now apply the speed formula.
Speed = Distance/Time.
Put value;
Speed = 0.6km/0.08h.
= 7.5km/h.
Distance = 600m = 600/1000 = 0.6Km.
Time = 5 minutes = 0.08 hours.
Speed = ?.
Now apply the speed formula.
Speed = Distance/Time.
Put value;
Speed = 0.6km/0.08h.
= 7.5km/h.

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.

s = d/t.
600/300 m/sec,
= 2 m/sec.
2 * 18/5 km/hr.
s = 36/5 kmph.
600/300 m/sec,
= 2 m/sec.
2 * 18/5 km/hr.
s = 36/5 kmph.

Guy's those who don't know how 18 comes.
Here is the answer 3.6 multiply 5=18?
