Question

a car covers a distance of 300 km with a speed of 60 km per hour and then covers the distance of 450 km with a speed of 90 km per hour. Find its average speed.​

Answer 1

Answer:

75 km/hr

Explanation:

Car covers a distance = 300/60= 5 hrs

Car covers a distance = 450/90= 5 hrs

Total Time = 10 hrs

Total Distance = 300+450= 750km

Average speed= Total Distance/Total Time taken

= 750/10 = 75km/hr
