A businesswoman’s flight leave Montgomery at 2pm and arrives in Hartford at 9:45pm. Express the duration of the flight as a mixed number

Sagot :

The duration of the flight as a mixed number is 5³/₄ hours

Time

This is the duration of an event. It is measured in seconds. Other units of measurement are days, months, years etc.

Duration of flight

The duration of the flight T = t' - t where

  • t = start time and
  • t' = end time

Since the flight leaves Montgomery at 2 pm, t = 2:00 pm. Also, the flight arrives at Hartford at 9:45 pm, t' = 9:45 pm

Since, T = t' - t

Substituting the values of the variables into the equation, we have

T = 9:45 - 2:00

T = 5:45 hours

Converting the minutes to hours, we have since 60 minutes = 1 hour

T = 5⁴⁵/₆₀

T = 5³/₄ hours

So, the duration of the flight as a mixed number is 5³/₄ hours
