Answer 1

250+520=770/55*5/18=50.4sec

Answer 2

Answer:

50.4 seconds

Step-by-step explanation:

Given, Speed = 55 km/hr

                       = 55 * (5/18) m/sec

                       = (275/18) m/sec

Total Distance = 250 + 520

                        = 770 m.

∴ Time = Distance/Speed

            = (770 * 18)/275

            = 50.4 seconds.

Therefore, the time it takes is 50.4 seconds.

Hope it helps!
