Answer 1

Answer: 0.4469 m/s

Explanation:

First, convert mile into meters.

1 mile = 1609 m

Secondly, convert hour into seconds

1 hour = 3600 s

Finally, convert 1.000 mph to meters per second.

1.000 mph is same as 1 mile / 1 hour

Put SI units we converted earlier.

1 mile / 1 hour = 1609 m / 3600 s

1 mile / 1 hour = 0.4469 m/s
