Answer:
Speed in meter per second = 31.94 m/s
Speed in miles per hour = 71.46 miles/h
Explanation:
Speed is measure of distance traveled per unit time. It is :
[tex]Speed=\frac {Distance}{Time}[/tex]
Given the speed = 115 km/ h
Considering, 1 km = 1000 m
Also, 1 h = 3600 s
So,
[tex]Speed=\frac {115\times 1000\ m}{3600\ s}=31.94\ m/s[/tex]
Thus speed in meter per second = 31.94 m/s
Considering, 1 km = 0.621371 miles
So,
[tex]Speed=\frac {115\times 0.621371\ miles}{h}=71.46\ miles/h[/tex]
Thus, speed in miles per hour = 71.46 miles/h
