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

Answer:

0.52 km

Step-by-step explanation:

We are given that

Speed of object, v=$9\frac{9}{10}km/h$

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

Distance travel by object, s=$5\frac{1}{10}km$

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

$Time=\frac{Distance}{speed}$

Using the formula

Time taken by object to travel 5.1 km =$\frac{5.1}{9.9} hr$

Time taken by object to travel 5.1 km=0.52 hr
