Question

An object is traveling at a steady speed of 9 9/10 km/per hour about how long will it take the object to travel 5/1/10 km/per hour.

Answer 1

0.52 km

Explanation:

We are given that

Speed of object, v=
`9(9)/(10)km/h`

Speed of object, v=
`9+0.9=9.9km/h`

Distance travel by object, s=
`5(1)/(10)km`

Distance travel by object, s=
`5+0.1=5.1km`

We have to find the time taken by object to travel 5 1/10 km.

We know that

`Time=(Distance)/(speed)`

Using the formula

Time taken by object to travel 5.1 km =
`(5.1)/(9.9) hr`

Time taken by object to travel 5.1 km=0.52 hr
