A naval supply ship travels $150$ nautical miles in $10$ hours, and then travels an additional $90$ nautical miles in $5$ hours. What is the ship's average speed for the entire trip, in knots (nautical miles per hour)?

Cevap: 16 knots

Cevap

16 knots

The overall average speed is calculated correctly by finding the total distance (

150 + 90 = 240

nautical miles) and dividing it by the total time (

10 + 5 = 15

hours). This calculation (

240 \div 15

) results in exactly

16

knots.

Adım Adım Çözüm

Calculate the total distance traveled for the entire trip.

150 + 90 = 240

nautical miles

Finding average speed requires knowing the complete distance covered across all segments of the trip.

Calculate the total time taken for the entire trip.

10 + 5 = 15

hours

Finding average speed requires knowing the total elapsed time.

Divide the total distance by the total time.

240 \div 15 = 16

knots

The formula for average speed is Total Distance divided by Total Time.

Anahtar Kavram
