Question

WORTH 100 POINTS

Answer 1

Answer:

The problem does not work.

Step-by-step explanation:

The plane with speed of 31 mph will cover 640 miles in $\frac{640}{31} = 20.64$ hours.

Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.

So, it will burn in 20.64 hours $\frac{5 \times 20.64}{0.05} = 2064$ gallons.

Now, the helicopter with speed of 45 mph will cover 640 miles in $\frac{640}{45} = 14.22$ hours.

Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.

So, it will burn in 14.22 hours $\frac{7 \times 14.22}{0.083} = 1194.48$ gallons.

But both of them starts with only 80 gallons of fuel.

Therefore, the problem does not work. (Answer)
