Andre walks more steps than Priya.
To find out who many steps each one of them walks in a week, we have to carry out different calculations starting with Andre.
Calculation for number of steps taken by Andre
Andre takes 6000 steps in 50 minutes. We can use this information to scale up his number of steps over a period of 5 hours(300 minutes.). The quickest way to do this calculation, is to notice that there are 6 different 50 minute segments in 300 minutes. This means that the number of steps taken in 5 hours is
steps.
Another way to do this calculations is to use proportions
.
Andre takes 36000 steps that week.
Calculation for number of steps taken by Priya
The number of steps taken by Priya is given by the is given by the function
where
is the time in minutes. Priya walks for a total of 5 hours or 300 minutes. We calculate the number of steps she takes as shown below,

Priya takes a total of 35400 steps.
Since 36000 steps is greater than 35400 steps, we conclude that Andre walks more steps than Priya.

Answer:
2/45
Step-by-step explanation:
0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as:
. Multiplying the two fractions results in 4/90 which can be simplified to 2/45.
