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 directly divide 60/5 and multiply with 600 and divide it with 1000.
60/5*600/100 = 7.2.
60/5*600/100 = 7.2.

Simply,
(2/1000) = 0.002km/sec
Then (0.002*3600) = 7.2km/sec.
Note: small quantity to big quantity then divide i.e; 2/1000 = meter into kms.
(2/1000) = 0.002km/sec
Then (0.002*3600) = 7.2km/sec.
Note: small quantity to big quantity then divide i.e; 2/1000 = meter into kms.

= D/t
= 600/5 * 60 * 18/5,
= 7.2.
= 600/5 * 60 * 18/5,
= 7.2.

Speed = dis/time so speed = 600/5 convert it directly to km/hr (1 km= 1000m and1 hour = 60 minutes).
So, speed = 600*60/5*1000 = 7.2km/hr.
So, speed = 600*60/5*1000 = 7.2km/hr.
