The answer is 5 boxes. First we have to do 60 x 2 to find out the area of the walkway (120 ft). Then since the tiles are 2 by 2 feet and come in 6 boxes we do, 2 x 2 to find the area of 1 tile,which is 4 ft, then we multiply that by 6 to find out the total amount of tiles which is 24. We then divided 120 by 24 to find out how much boxes we will need which is 5. Hope that helped :)
Answer:
7 miles per hour
Step-by-step explanation:
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
Hope this helps :)
