Question

An aircraft carrier left Hawaii one hour before a fishing boat. The ships traveled in opposite directions. The fishing boat traveled at 5 mph for six hours. After this time the ships were 100 mi.apart. What was the aircraft carriers speed?

Answer 1

Answer: The speed of the aircraft carriers would be 28.33 mph.

Step-by-step explanation:

Since we have given that

Distance between the ships = 100 miles

Speed of the fishing boat = 5 mph

Number of hours = 6 hours

Let the speed of an air craft carrier be 'x'.

Since they are in opposite direction, so, our equation would be

$\dfrac{100}{6}=x+5\\\\33.33=x+5\\\\33.33-5=x\\\\x=28.33\ mph$

Hence, the speed of the aircraft carriers would be 28.33 mph.

Answer 2

Answer:

21.6 mph

Step-by-step explanation:

The fishing boat traveled 30 miles and the air carrier is 100 apart meaning its 130 miles. It's in 6 hours so you do 130 ÷ 6 = 12.6mph
