Answer:
He will require 5400 seconds
Step-by-step explanation:
Given:
The total distance he has to cover = 48 miles
The speed he is moving = 32 mph
To find :
Time in seconds = ?
Solution:
As given in the question that he is moving with a constant speed of 32 mph and he has to cover a distance of 48 miles at this speed so we will be using distance formula for finding the time taken by him
Formula is
Distance = speed * time
here we have to find time so
Time = 
Putting in the values we get
Time = 
Dividing it gives us
Time = 1.5 hours
As we need the answer in seconds and we know that
one hour has = 3600 seconds
so
Time = 1.5 * 3600 seconds
Time = 5400 seconds
