Step-by-step explanation:
Multiply the amount of feet in one mile by the amount of miles in the question(5,280 x 50 = 264,000)
Divide the amount of feet in 50 miles by the amount of minutes in 1 hour to get the amount of feet per mile (264,000 ÷ 60 = 4,400)
Divide the amount of feet per mile to get by the amount of seconds in a minute to get the amount of feet per second (4,400 ÷ 60 = 73.33)
Your answer rounded to the nearest whole number is 73
That's a lot of questions. First, they're asking for how much each person pledged. Ivan said he would give $4.25, plus $1.25 per mile. As an expression, that would be 1.25m+4.25 . Vicky said that she would give $5.75, plus $.75 per mile, which would be .75m+5.75 . The second problem asks you to add the two, so add 1.25m and .75m to get the total amount she would earn per mile, which is $2. If I got paid $2 for every mile I biked, I would bike a marathon. Then add the flat payments of $4.25 and $5.75, and you get $10. So, the final equation would be 2m+10.
The last question is asking for you to find an equivalent proportional expression. To find this, you can just dividing by the greatest common factor of the two numbers. I got 2, so the equation would be 1m+5.
3/7 (0.428571) Miles on Monday
2/6 = 1/3 (.333333) Miles on Tuesday
Subtract both numbers
.428571 - .333333 +
[Answer]: 0.095238
or 2/21 More miles on Monday.
