Question

a journey takes 3 hours at an avereage speed of 45 km/pr. How long will the same journey take at an average speed of 60 km/pr?​

Answer 1

Time taken is 2.25 hrs

Here is the solution

Answer 2

Answer:

2 hrs 15 mins

Step-by-step explanation:

speed(1)=45km/hr

time(1)=3hrs

so distance covered or the distance of journey=speed*time=45*=135km

speed(2)=60km/hr

lets suppose

time(2)=x hrs

so

distance of journey=speed *time

135=60*x

so x=2.25 hrs

that is 2 hrs and 15 mins
