If the velocity of a bicycle is 10 m/s how long will it take to cover a distance of 18 km<br>

Sergeeva-Olga [200]

Answer:

time taken=1800 seconds

Step-by-step explanation:

velocity=v=10m/s

distance=S=18km=18×10³m=18000m

t=?

as we know that

velocity= $\frac{distance covered}{time taken}$

velocity×time taken=distance covered

now here we have to find time

time taken= $\frac{distance covered}{velocity}$

time taken= $\frac{18000m}{10m/s}$

time taken=1800seconds
