Given :

  • Speed = 60 km per hour
  • Time = 1 hour 20 minutes

To Find :

  • Distance = ?

Solution :

We are given :

Time = 1 hour 12 minutes

We know that :

1 hour = 60 minutes

 \sf : \implies 1 minute = \dfrac{1}{60} \: hours

 \sf : \implies 1\: hour \: 60 \: minutes = 1 + \dfrac{12}{60} \: hours

 \sf : \implies 1\: hour \: 60 \: minutes = 1 + \cancel{\dfrac{12}{60}} \: hours

 \sf : \implies 1\: hour \: 60 \: minutes = 1 + \dfrac{1}{5} \: hours

 \sf : \implies 1\: hour \: 60 \: minutes = \dfrac{5}{5} + \dfrac{1}{5} \: hours

 \sf : \implies 1\: hour \: 60 \: minutes = \dfrac{5+1}{5} \: hours

 \sf : \implies 1\: hour \: 60 \: minutes = \dfrac{6}{5} \: hours

Now, we know that :

 \underline{\boxed{\bf Distance = speed \times time}}

We have :

  •  \sf Time = \dfrac{6}{5} \: hours

  • Speed = 60 km/hour

By filling values :

 \sf : \implies Distance = 60 \: km/hour \times \dfrac{6}{5} \: hours

 \sf : \implies Distance = \cancel{60} \: km \times \dfrac{6}{\cancel{5}}

 \sf : \implies Distance = 12 \: km \times 6

 \sf : \implies Distance = 72\: km

 \underline{\boxed{\bf Distance = 72\: km}}

Hence, The car will cover the distance of 72 km.
