Question

bus cover a certain distance in 4 hours 20 minutes at an average speed of 60 km per hour how long will it take to cover the same distance at speed of 40 km per hour​

Answer 1

Answer:

6 hrs 30 min

Step-by-step explanation:

Avg. spd = 60 km/hr

Time = 4 hr 20 min = 4+1/3 hrs = 13/3 hrs

So distance = 60*13/3 = 260 km

Now, dist. = 260 km, spd = 40km/hr

So, time taken to cover = 260/40 = 6.5 hrs = 6 hrs 30 min
