Answer:
B) 30min
Step-by-step explanation:
Start with 2 and continue to multiply that by 2 until you get 128
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
Then start with what you think could be the right answer based on how many intervals there are.
You know it can't be 15 because there definitely isn't enough and you know its not 1hr because theres way more than 3.
So you're left with either B) 30min or C) 45min
It has to be B) 30min because there are 6 intervals and 30min goes into an hour twice, meaning that if every 2 intervals is an hour there are 3 hours.
Im pretty sure you need to divide 155 by 4 or 48. try it and see what you get. then ask your teacher if you did it right. always ask questions.
Answer:
He runs about 30 miles (29.75)
Step-by-step explanation:
4 miles per day for 7 days is 28 miles
(4+4+4+4+4+4+4)
add up the additional quarter mile per day for 7 days which is
(.25+.25+.25+.25= 1 mile, +.25 +.25 +.25= .75 mile)
add these miles to the 28
(1+28+.75)
Final answer=29.75
Well here's my work:
=16(2)+24
=32+24
=56
So 56 seconds.
