Answer 2

Answer:

Hey mate,

In this problem we need to suppose that the car is travelling at a uniform speed of 45km/hr

So first we need to find the distance the car travels in 6 hrs..

               Distance = Speed × Time

                              = 45 × 6

                             = 270 km

Now we need to find at which speed can the car complete the journey in 5 hrs

             ∴ Speed =  $\frac{Distance}{Time}$

                            =  $\frac{270}{5}$

                           = 54 km/hr

∴ The car needs to travel at a speed of 54 km/hr to complete the journey of 270 km in 5 hours..
