The speed limit on some interstate highways is roughly 115 km/h. what is the meters per second? how many miles per hours is this?

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 :

Given the speed = 115 km/ h

Considering, 1 km = 1000 m

Also, 1 h = 3600 s

So,

Thus speed in meter per second = 31.94 m/s

Considering, 1 km = 0.621371 miles

So,

Thus, speed in miles per hour = 71.46 miles/h
