Answer 2

Answer:

The distance traveled is 375 m.

Step-by-step explanation:

Given : Speed of a man is 45 km per hour

To find : The distance traveled by man in 30 seconds

Solution : First we convert km/hr into m/s

1 km = 1000 m

1 hour = 60 × 60 seconds

$1\text{km/hr} =\frac{1000}{60\times60}=\frac{5}{18}\text{m/s}$

$45\text{km/hr} =\frac{45\times5}{18}\text{m/s}$

Speed $=\frac{45\times5}{18}\text{m/s}$ and Time = 30 s

$Distance = Speed \times Time$

$Distance = \frac{45\times5}{18}\times 30$

$Distance = 375 m$

Therefore,The distance traveled is 375 m.
