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.

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.

S = d/t.

600m = 0.6km.

5minutes = 5/60 = 0.083hr,

S = 0.6/0.083,

= 7.2km/hr.

600m = 0.6km.

5minutes = 5/60 = 0.083hr,

S = 0.6/0.083,

= 7.2km/hr.

D = S*T.

D = 600m,

T = 5 mints => 5 * 60 = 300 sec.

S = D/T = 600/300 = 2 m/sec.

convert m/sec to km/hr,

2*18/5 = 7.5.

D = 600m,

T = 5 mints => 5 * 60 = 300 sec.

S = D/T = 600/300 = 2 m/sec.

convert m/sec to km/hr,

2*18/5 = 7.5.

We have to convert meters per minute to kilometers per hour.

1 km = 1000 m

Therefore,

Speed = Distance/Time.

Speed = (600 m/5 min) * (60 min/1 hr) * (1 km/1000 m),

Speed = 12 km/hr.

Therefore, the person's speed is 12 km/hr.

1 km = 1000 m

Therefore,

Speed = Distance/Time.

Speed = (600 m/5 min) * (60 min/1 hr) * (1 km/1000 m),

Speed = 12 km/hr.

Therefore, the person's speed is 12 km/hr.

600/5=120m

60*120=7200

7.2km.

Correct me, If I am wrong.

60*120=7200

7.2km.

Correct me, If I am wrong.

Distance= 600m

= 0.6km

Time = 5mins.

=5/60hrs.

Speed = D/T.

= 0.6/0.08333.

= 7.2km/hr.

So, Speed = 7.2km/hr.

= 0.6km

Time = 5mins.

=5/60hrs.

Speed = D/T.

= 0.6/0.08333.

= 7.2km/hr.

So, Speed = 7.2km/hr.
