Solution

The correct option is C 113 s
Here, we are given that
Time = Distance ÷ Speed
Rounding off 56535m and 452m/s to the nearest hundred we get 56500m and 500m/s respectively ( Comparing tens digit in both numbers, we have 5 ≥ 5, so we round the numbers up to the next hundred)
so,
Time = 56500m ÷ 500m/s = 113s
Therefore, the correct option is c)
