Answer: 126s for a)
Step-by-step explanation:
Time = Distance ÷ Speed
Distance = 756m
Speed= 6 metres per second
756m ÷ 6m/s = 126s
(sorry I can't include how exactly to divide the numbers. I would need some sort of drawing board to show it)
cancel out the 2 "m" units in the numbers as well as the division sign and the / in the "m/s" and you are left with seconds as the final unit for your answer
