Answer:
0.52 km
Step-by-step explanation:
We are given that
Speed of object, v=[tex]9\frac{9}{10}km/h[/tex]
Speed of object, v=[tex]9+0.9=9.9km/h[/tex]
Distance travel by object, s=[tex]5\frac{1}{10}km[/tex]
Distance travel by object, s=[tex]5+0.1=5.1km[/tex]
We have to find the time taken by object to travel 5 1/10 km.
We know that
[tex]Time=\frac{Distance}{speed}[/tex]
Using the formula
Time taken by object to travel 5.1 km =[tex]\frac{5.1}{9.9} hr[/tex]
Time taken by object to travel 5.1 km=0.52 hr
