Answer:
5/3 hours ( answer in fraction )
1.66 hours ( answer in decimal )
Step-by-step explanation:
Given,
Distance ( d ) = 15 kilometer ( 15 km )
Velocity ( v ) = 9 kilometers per hour ( 9 km / h )
To find : Time ( t )
Formula : -
v = d / t
t = d / v
= 15 / 9
t = 5/3 hours
( or )
t = 1.66 hours ( approximately )
Note : -
1. If the sentence " rate of kilometers " is there, then it is velocity.
2. If the sentence " How long will it take " is there, then it is time.
