Answer:
1800 seconds
Step-by-step explanation:
Given,
Distance ( d ) = 18 km
Velocity ( v ) = 10 m/s
To find : Time ( t ) = ?
Distance in km need to be converted to m.
1 km = 1000 m
18 km
= 18 x 1000
= 18000 m
So,
d = 18000 m
Formula : -
v = d / t
t = d / v
= 18000 / 10
t = 1800 seconds.
Therefore,
1800 seconds long, it will take to cover a distance of 18 km.
