9------1

15-----?

We divide 9 by 9 to get 1 so we divide 15 by 9 to get ?

15 / 9 = 1.66667

Answer 2

5/3 hours ( answer in fraction )

1.66 hours ( answer in decimal )

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.
