Question

1 hour=9 miles

Answer 1

40=6 miles
20=3 miles
1:20=12 miles
2:20=21 miles
10min =1.5 miles
1:40=15 miles

Answer 2

Answer:

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
