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 can solve it in this way;
First, divide 60 by 5, as 1 hour is 60 minutes.
So 60/5 = 12.
Now, multiply the quotient by 600m - 600 * 12 = 7200m or 7.2k.
First, divide 60 by 5, as 1 hour is 60 minutes.
So 60/5 = 12.
Now, multiply the quotient by 600m - 600 * 12 = 7200m or 7.2k.

Distance = 600 m = 0.6 km.
Time = 5 minutes = 5/60 = 1/12 hour.
Speed = Distance/Time.
= 0.6 ÷ (1/12),
= 0.6 × 12,
= 7.2 km/h.
Time = 5 minutes = 5/60 = 1/12 hour.
Speed = Distance/Time.
= 0.6 ÷ (1/12),
= 0.6 × 12,
= 7.2 km/h.

600m = 0.6km.
t = 5min
means(5/60) = 1/12.
then 0.6/1/12,
=7.2.
t = 5min
means(5/60) = 1/12.
then 0.6/1/12,
=7.2.

Km defines distance.
Hr defines time.
Question is to find speed?
S = km/hr.
1. To find m to km.
1 Meter to 1000km.
600Meter is 600/1000 = 0.6km.
2. To find min to hr.
60 min =1hr.
5/60 = 0.08hr.
Finally.
S = KM/hr
= 0.6/0.08
= 7.5km/hr.
Hr defines time.

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.
