Question

A journey takes 6 hours if I travel at 50 km an hour .How long will it take to travel at 60 km an hour​

Answer 1

Answer:

5 hr

Step-by-step explanation:

Let the distance be 'd'. Using speed = distance/time.

If speed is 50 km/hr,

=> 50 = d/6

=> 300 = d

If speed is 60 km/hr,

=> 60 = d/time

=> 60 = 300/time

=> time = 300/60

= 5

Answer 2

Step-by-step explanation:

Use the formula of indirect proportion;

=a×b=c×d

=>6×50=c×60

=>c=6×50/60=5 hrs.
