Question

A small airplane flew 140 miles in 50 minutes. At this rate, how many miles can it fly in one hour (60 minutes)?

A) 120 miles
B) 150 miles
C) 140 miles
D) 160 miles

Answer 1

To determine how many miles the airplane can fly in one hour, calculate its speed in miles per minute and multiply by 60 minutes. The calculated distance is 168 miles, so the closest answer option is D) 160 miles.

Step-by-step explanation:

A small airplane flew 140 miles in 50 minutes. To calculate how many miles it can fly in one hour (60 minutes), we need to find the airplane's speed in miles per minute and then extend that to an hour.

First, we find the speed:

• Speed = Distance / Time
• Speed = 140 miles / 50 minutes = 2.8 miles per minute

Now, we calculate how many miles it can fly in one hour:

1. 1 hour = 60 minutes
2. Total miles in one hour = Speed * Time
3. Total miles in one hour = 2.8 miles/minute * 60 minutes
4. Total miles in one hour = 168 miles

Therefore, the answer is D) 160 miles, which is the closest whole number to our calculated distance.
