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.

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

Time = 5 min.

Distance = 600 meter.

Distance = 600/5 = 120m in one minute.

In hour = 120x60 = 7200m in one hour.

1km = 1000m.

7200m = 7.2m=>answer.

Distance = 600 meter.

Distance = 600/5 = 120m in one minute.

In hour = 120x60 = 7200m in one hour.

1km = 1000m.

7200m = 7.2m=>answer.

600m = 5 minutes, 120m = 1 minutes (600/5),

1 hour = 60 minutes,

7200m = 60 minutes (120*60),

1000m = 1 km.

7200m = 7.2 km.

1 hour = 60 minutes,

7200m = 60 minutes (120*60),

1000m = 1 km.

7200m = 7.2 km.

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.

1000 meter = 1 kilometer.

3600 seconds = 1 hour.

1000 meter/3600second=1 kilometer/1 hour.

5 meter/18 second = 1 kilometer/1 hour.

3600 seconds = 1 hour.

1000 meter/3600second=1 kilometer/1 hour.

5 meter/18 second = 1 kilometer/1 hour.

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.

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.

We know,

1 min = 60 sec.

5 min = 60 * 5 = 300 sec.

A/c to question;

Distance = 600 m.

Time = 300 Sec.

Now speed = Distance/ Time = 600/ 300 = 2 m/s.

Converting km to meter, multiply with 18/5.

Now, 2*18/5 = 36/5 = 7.2 km/hr.

1 min = 60 sec.

5 min = 60 * 5 = 300 sec.

A/c to question;

Distance = 600 m.

Time = 300 Sec.

Now speed = Distance/ Time = 600/ 300 = 2 m/s.

Converting km to meter, multiply with 18/5.

Now, 2*18/5 = 36/5 = 7.2 km/hr.
