Question

Katherine sped up to 65 miles per hour. Calculate this speed in meters per second.

Answer 1

Answer:

29.06 m/s

Explanation:

Answer 2

Explanation:

65 mi/hr × 1 hr/60 mins × 1 min/60 secs × 1 mi/1609.34m

The units hour, minutes, and miles cancel out. It's easier to notice when writing on paper versus typing.

Now multiple the numerators and divide by the denominators

Numerators: 65 × 1 × 1 × 1 = 65

Denominators: 1 × 60 × 60 × 1609.34 = 5793624

65 m ÷ 5793624 s = 0.0000112192 m/s

Round to appropriate sig figs

0.000011 m/s

This answer sounds wrong, but this is my thinking. Hopefully it helps in some way
