Tony has 50 miles to his destination after 21 minutes of driving and he has 40.4 miles to his destruction after 33 minutes of driving. How many miles will he have to his destination after 37 minutes of driving?

37.2

Step-by-step explanation:

After driving 21 minutes, he has 50 miles to go.

After driving 33 minutes, he has 40.4 miles to go.

Between 21 minutes and 33 minutes, he drove for 33 min - 21 min = 12 minutes.

In those 12 minutes of driving, he drove from a distance of 50 miles to a distance of 40.4 miles to his destination.

50 miles - 40.4 miles = 9.6 miles.

He drove 9.6 miles in 12 minutes.

We can find his speed in miles per minute.

(9.6 miles) / (12 minutes) = 0.8 miles/minute

The time after 37 minutes of driving is 4 minutes after the time after 33 minutes of driving, so he is driving 4 minutes more than when he was 40.4 miles from his destination.

0.8 miles/minutes * 4 minutes = 3.2 miles

He drove 3.2 miles in 4 minutes.

He was 40.4 miles away from his destination at 33 minutes. He is 3.2 miles closer at 37 minutes.

40.4 miles - 3.2 miles = 37.2 miles

Answer: He has 37.2 miles to his destination after 37 minutes of driving.
