initial speed=60km/h

time taken= 15hours

distance=speed×time

distance =15×60=900km

new time taken=12 hours

new speed=900/12=75km/h

Answer:

distance = speed × time

distance of journey = 60 × 15 km

now the person has to travel the same distance but in less time

let us reverse the relation

speed \:  =  \frac{dista nce \: }{time}  \\ speed \:  =   \frac{15 \times 60}{12}  \\ speed = 75kmh
