Lets say 10 add a 0 = 100 9.5 add a 0 = 95.0 (move ok decimal place) so there is a 5% error.
there are four terms in this expression with each factor
45x5 = 225 minutes a week
225 x 12 = 2700 minutes in 12 weeks
2700 / 60 = 45 hours
1800 / 45 = 40 laps per hour
answer: average 40 laps per hour
Answer:
It took 5 hours
Step-by-step explanation:
Because 28 times 5 is 140 plus 25 for the call is 165.
Pages read by Arnold in 7 minutes = 3 pages
Pages read by Arnold in 1 minutes
= 3/7 pages
= 6/14 pages
Pages read by Brenda in 14 minutes = 8 pages
Pages read by Brenda in 1 minutes = 8/14 pages
(6/14) < (8/14)
So, speed of Arnold < speed of Brenda.
So, Brenda reads faster.
