Answer 2

The vehicle will take 12 hours to travel 912km and it will travel 532km in 7 hours with a speed of 76km/hr.

GIVEN: Car travels= 228 km; Time taken = 3 hours

TO FIND: How long it will take to travel 912 km and how far will it travel in 7 hours

SOLUTION:

We are provided the information of car which travels 228km in 3 hours. so from the given information, we can find the speed of the vehicle.

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

  Distance is 228km and time taken is 3 hr.

              = $\frac{228}{3}$

              = 76 km/hr.

The speed of the vehicle is 76km/hr.

Now we need to find how much time it will take to travel 912 km and we have distance and speed.

With the help of the same formulae, we can get time.

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

        = $\frac{912}{76}$

      = 12 hours

Time is taken for a vehicle to travel 912km with a speed of 76km/hr. is 12 hours.

Now we need to find the distance covered by the vehicle in 7 hours.

Distance = Time × Speed

                 = 7 × 76

               = 532 km

532 Km is the distance covered by the vehicle in 7 hours.

The vehicle will take 12 hours to travel 912km and it will travel 532km in 7 hours with a speed of 76km/hr.
