40 minutes= 6 miles
20 minutes= 5 miles
1 hour and 20 minutes = 12 miles
2 hours and 20 minutes = 21 miles
10 minutes= 1.5 miles
1 hour 40 minutes = 15 miles.
Step-by-step explanation:
Given
1 hour = 9 miles
2 hours = 18 miles
Solve for 40 min
If 1 hour = 9 miles,
∴ 40 = ? miles
To find,
first, convert 1 hour to minutes
Which is 60 minutes,
Second, set an equation:
60/9 = 40/?
Next, divide 60/9:
6.66666666667 in nearest tenths would be 6.7
Lastly, divide 40 and 6.7
which is 5.97 in nearest tenths is 6
Therefore, the 40 minutes= 6 miles
Solve for 20 minutes
If 1 hour = 9 miles,
∴ 20 =? miles
To find,
first, convert 1 hour to minutes
Which is 60 minutes,
Second, set an equation:
60/9 = 20/?
Next, divide 60/9:
6.66666666667 in nearest tenths would be 6.7
Lastly, divide 20 and 6.7
which is 2.98 in nearest tenths is 3
Therefore, 20 minutes=3 miles
Solve for 1 hour and 20 minutes
If 1 hour = 9 miles,
and 20 minutes is 3 miles,
then you have found your answer. Simply add them both.
9 + 3 = 12
Therefore, 1 hour and 20 minutes = 12 miles
Solve for 2 hours and 20 minutes
If 2 hours = 18 miles,
and 20 minutes is 3 miles,
then you have found your answer. Simply add them both.
18 + 3 = 21
Therefore, 2 hours and 20 minutes = 21 miles
Solve for 10 minutes
If 1 hour = 9 miles,
∴ 10 =? miles
To find,
first, convert 1 hour to minutes
Which is 60 minutes,
Second, set an equation:
60/9 = 10/?
Next, divide 60/9:
6.66666666667 in nearest tenths would be 6.7
Lastly, divide 10 and 6.7
which is 1.49 in nearest tenths is 1.5
Therefore, 20 minutes = 1.5 miles
Solve for 15 miles
If 9 miles = 1 hour,
∴ 15 miles =?
Second, set an equation:
9/60 = 15/?
Next, divide 60/9:
6.66666666667 in nearest tenths would be 6.7
Lastly, multiply 15 and 6.7
which is 100.5 in nearest tenths is 100
Therefore, 15 miles = 1 hour 40 minutes
