At 80 km per hour it takes loida 3 hours to travel from her house to their school how long will it take her if she travels at 60 km/h

[tex]\sf{\underline{{Answer:}}}[/tex]

'We will use the formula "D = st" to find the distance from her house to her province which is 180 km remember that distance is equal to the product of time and speed.

  • [tex] \tt{D = st}[/tex]
  • [tex] \tt{D = ( 60\:\:kph ) ( 3\:\: hours ) }[/tex]
  • [tex] \tt\green{D = 180\:\: km}[/tex]

'Now let's use the formula "T = d/s" To find the time divide the distance by its speed. If we have 180 km distance and if she travels 80 km/hr then the time is :

  • [tex] \tt{T = \frac{d}{s}}[/tex]
  • [tex] \tt{T = \frac{180\:\: km}{80\:\: kph}}[/tex]
  • [tex] \tt\green{T = 2.25 \:\:hours}[/tex]

Hence, if loida travels 80 kilometer per hour then the time is 2.25 or 2 hours and 25 minutes.
