Question

Driving at 165mph how many seconds does it take to travel 1.5 miles

Answer 1

Hi Rex, you need to convert miles per hour to miles per second. Here's how:

 

miles/hours * hours/minutes * minutes/seconds

 

This becomes:

 

165 miles/1 hour * 1 hour/60 minutes * 1 minute/60 seconds

 

The hour terms cancel and so do the minutes leaving only miles per seconds, or 165/3600, which is ≈ .046 miles per second.

 

Therefore, the number of seconds to go 1.5 miles is .069 seconds.

Answer 2

d = r · t

d / r = t

1.5 / 165 = t

0.009090 = t

0.009090(3600) = t

32.7272 = t
