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.

Speed = Distance/Time.
Distance = 600 m = 600/1000 = 0.6 km
Time = 5 min = 5/60 = 0.083 min.
Speed = 0.6/0.083 = 7.2 km/hr.
Distance = 600 m = 600/1000 = 0.6 km
Time = 5 min = 5/60 = 0.083 min.
Speed = 0.6/0.083 = 7.2 km/hr.

s = d/t.
d = 600m,
t = 5m.
600/5 * 60,
= 2 * 18/5,
= 2 * 3.2,
= 7.2.
d = 600m,
t = 5m.
600/5 * 60,
= 2 * 18/5,
= 2 * 3.2,
= 7.2.

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.

Given:
Distance = 600m(m=meter)
Time = 5minutes.
Formula:
=> speed = distance/time
=> 1 hour = 60 minutes
=> 1 Km = 1000m.
Speed = 600/5.
120m(minutes).
(To convert minutes into hours we need to multiply the number by 60).
speed = 120 * 60 = 7200h(an hour)
(To convert meters into kilometres we need to divide the number by 1000)
speed = 7200/1000 = 7.2km/h (kilometre per hour)
Distance = 600m(m=meter)
Time = 5minutes.
Formula:
=> speed = distance/time
=> 1 hour = 60 minutes
=> 1 Km = 1000m.
Speed = 600/5.
120m(minutes).
(To convert minutes into hours we need to multiply the number by 60).
speed = 120 * 60 = 7200h(an hour)
(To convert meters into kilometres we need to divide the number by 1000)
speed = 7200/1000 = 7.2km/h (kilometre per hour)

0.6 * 60 ÷ 5 = 7.2 is the answer.

Speed = Distance ÷ time.
Speed = 600÷(5×60).
Speed = 2 m/sec,
Now, convert into kmph.
i.e.,S = 2×(18÷5).
Then S = 7.2 kmph.
Speed = 600÷(5×60).
Speed = 2 m/sec,
Now, convert into kmph.
i.e.,S = 2×(18÷5).
Then S = 7.2 kmph.
