Answer:
= 0.38 m/s
Step-by-step explanation:
▪Total distance = 800 m
5 min = 100 m
▪Remaining distance = 800 - 100 = 700 m
20 min = 700 m
▪Total time taken = 20 + 10 + 5 = 35 min
If 1 min = 60 sec
What about 35 min = ?
= 35 x 60
= 2100 sec
▪Average speed = TD ÷ TT
= 800 ÷ 2100
= 0.38 m/s
1.25 hours for each lawn. 1.25 x 7 = 8.75.
Answer:
just add 8+8+8 until you get to the number u want/need and the same with 7. Or you can multiply.
8x1=8
7x1=7
8x3=24 (8+8+8=24)
7x3=21 (7+7+7=21)
etc.
Hope it helps!

Answer:
3b+3s
Step-by-step explanation:
According to the statement, Kharon needs to write 3 book reports with b pages. This means that he has 3 books and each of them has b amount of pages which you can express as b+b+b that is equal to 3b. Also, he has 3 science reports with s pages which is 3s. In order to find the total number of pages, you have to add up 3b plus 3s. According to this, the algebraic expression for the total number of pages Kharon will need to write is: 3b+3s.
