The distance you should cover is: S=150 km
Your average speed is: v=50 km/h
Therefore, to calculate the time you will take to cover this distance, we can use the basic relationship between space, distance and time, and we find:
[tex] t=\frac{S}{v}=\frac{150 km}{50 km/h}=3 h [/tex]
so, you will take 3 hours.
The average speed is the ratio of the length of path and time taken.
The time required to arrive at the cousin's house for the party is 3 hours.
What is average speed?
The average length of path covered by any object in a given interval of time is known as average speed.
Given data -
The distance between the house and city is, d = 150 km.
The average speed is, v = 50 km/hr.
The expression for the average speed of an object is given as,
v = d/t
here,
t is the time taken by an object to cover the average distance.
Solving as,
50 = 150 / t
t = 150 / 50
t = 3 hrs
Thus, we can conclude that the time required to arrive at the cousin's house for the party is 3 hours.
