Question

a bus takes 4 hours to reach a destination by travelling at 45km/hr. How long will it take while travelling at 60km/hr? No spamming ​ ​

Answer 1

Answer:

Correct option is A)

Let the car takes x hours to reach a destination by travelling at the speed of 80 km/h. Then,

Speed (in km/hr)6080Time (in hours)2xClearly, more the speed, less will be the time taken. So, it is a case of inverse proportion.

∴60×2=80×x⇒x=8060×2=23

Hence, the time taken will be 121 hours.
