Two planes are 1,400 miles apart. They fly towards each other, one at 125 mph and the other at 175 mph. How long does it take the planes to pass each other (round to the nearest hundredth)?

d = 125t + 175t = 1400,

300t = 1400,
t = 1400 / 300 = 4.67 hrs.

To find out how long it takes for the planes to pass each other, we need to consider their combined speed. The two planes are flying towards each other, so we can add their speeds together.

The first plane is flying at a speed of 125 mph, and the second plane is flying at a speed of 175 mph. So, the combined speed of the planes is 125 + 175 = 300 mph.

Now, we can determine how long it takes for the planes to pass each other by dividing the distance between them by their combined speed.

The distance between the planes is 1,400 miles.

To calculate the time it takes for the planes to pass each other, we use the formula: Time = Distance / Speed.

Time = 1,400 miles / 300 mph.

Dividing 1,400 by 300 gives us approximately 4.67 hours.

Rounding this to the nearest hundredth, we find that it takes about 4.67 hours for the planes to pass each other.
