Question

A car takes 2 hours to reach a destination by travelling at 60km/hr . How long will it take while travelling at 80km/hr ?​

Answer 1

Answer:  It will take one and a half hour to travel.

Step-by-step explanation:

since time = 2 hours

speed = 60 km/hr

therefore distance to the destination = speed * time

                                                             = 60 *2

                                                              = 120 km

now speed changes  to 80km/hr

so time taken = distance /time

                      = 120/80

                       = 3/2 hr

                    = 1.5 hr

Hope this helped!!
