Question

If a bus can travel 240 km in 4 hours, how many hours does it take to travel 420 km with the same speed ?

Answer 1

Bus travel velocity is 240/4=60km/hr
So hrs taken to travel 420 km= 420/60=7 hrs

Answer 2

Answer:

7 hours.

Step-by-step explanation:

time it takes to travel 240 km = 4 hours.

time it will take to travel 1 km = $\frac{4}{240} = \frac{1}{60}$.

time it will take to travel 420 km = $\frac{1}{60} \times 420$ = 7.

hence, it will take 7 hours to travel 420 km.
