Time taken to cover 120 kms is either $2.4$ hrs or $2$ hr $24$ mts

Speed per hour $=60km$
The distance covered in 2 hours $=60 xx 2= 120$ kms

Total distance covered is $120$ kms

The same distance has to be covered at a speed of $50$ kms/hour

Time taken to cover 50 kms is $=1$ hr
Time taken to cover 1 km is $=1/50$ hr
Time taken to cover 120 kms is $1/50xx120=2.4$ hrs

[ $0.4$ hour is $0.4xx60=24$ minutes}

Time taken to cover 120 kms is either $2.4$ hrs or $2$ hr $24$ mts
