Answer:
The sped of car is 224 miles per hour faster than speed of human
Step-by-step explanation:
Given as :
The distance cover by human = d = 2.5 miles
The time taken by human to cover distance = t = 7 days
∵ 1 day = 24 hours
∴ 7 days = 7 × 24 = 168 hours
So, Human taken 168 hours to cover distance of 2.5 miles
Let The speed of human = s mi/h
∵ Speed = Distance × time
So, s = 2.5 miles × 168 hour
∴ s = 420 mi/h
So, The speed of human = s = 1.875 mi/h
Again
The time taken by car to cover distance of 2.5 miles = T = 45 minutes
I.e T = [tex]\dfrac{45}{60}[/tex] = 0.75 hour
Let The speed of car = s mi/h
∵ Speed = Distance × time
So, S = 2.5 miles × 0.75 hour
∴ S = 1.875 mi/h
So, The speed of car = S = 1.875 mi/h
The speed of car as compare to human
Speed of human = n × speed of car
Or, n = [tex]\dfrac{\textrm speed of human}{\textrm speed of car}[/tex]
Or, n = [tex]\dfrac{420}{1.875}[/tex]
∴ n = 224
Hence, The sped of car is 224 miles per hour faster than speed of human Answer
