Question

Change a speed of 72.4 miles per hour to its equivalent in meters per second.

Answer 1

Answer:

Speed in meter/sec will be 32.1777 m /sec  

Explanation:

We have given speed = 72.4 miles per hour

We have to convert this speed in meter per second

We know that 1 miles = 1.6 km

So 72.4 miles = 72.4×1.6= 115.84 km

We also know that 1 km = 1000 m

So 115.84 km $=115.84\times 10^3m$

We know that 1 hour = 60×60 = 3600 sec

So $72.4miles/hour=\frac{72.4\times 1600m}{3600sec}=32.1777m/sec$
