Aplane flew between two cities at 330 mph, a car went the same distance at 55 mph . if the car took 7.5 hours longer how far apart were the two cities

The cities are 495 miles apart.

Step-by-step explanation:

Let x represent the distance between the two cities.

Let t represent the time taken by the plane to fly between the two cities.

The plane flew between two cities at 330 mph.

Distance = speed × time

Distance covered by the plane would be

330 × t = 330t

A car went the same distance at 55 mph. If the car took 7.5 hours longer, means that the time spent by the car would be (t + 7.5) hours and distance travelled would be

55(t + 7.5) = 55t + 412.5

Since the distance is the same, then

330t = 55t + 412.5

330t - 55t = 412.5

275t = 412.5

t = 412.5/275

t = 1.5

the distance between the two cities would be

1.5 × 330 = 495 miles

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

the answer is stop cheating on things stoopid
