Answer:

72 Km per hour

Step-by-step explanation:

Speed = Distance/Time

60 = Distance/ (1.2 Hrs)

i.e 1 hour 12 mins = 1 + 12/60

= 1 + 1/5

= 1 + 0.2 = 1.2 hrs.

Distance = 60 x 1.2

Distance = 72 Kms.

Now new time is 1 hour.

Therefore, Speed = Distance/Time

Speed = 72/1

Speed = 72 Km per hour.
