Question

A car travels 60.0 miles per hour. What is its velocity in m/s? (1 km = 0.621 mi). . A] 0.01 m/s. .B] 0.03 m/s. .C] 9.66 m/s. . D] 26.8 m/s

Answer 1

By converting miles in to meter 
60 miles=96560 meter
1 hour = 3600 seconds
velocity= 96560m/3600s
Velocity= 26.8 m/s

Answer 2

Answer:

$v = 26.8 m/s$

so the speed in SI unit will be 26.8 m/s

Explanation:

speed of the car is given as

$v = 60 miles/hour$

so we will have

$1 miles = 1609 meter$

$1 hour = 3600 s$

now we know that

$v = 60 (\frac{miles}{hour}) \times (\frac{1609 m}{1 mile})\times (\frac{1 hour}{3600 s})$

$v = 26.8 m/s$

so the speed in SI unit will be 26.8 m/s
