How long does it take to travel 90 miles by car?

Answer 1

That depends on how fast the car is going. So if the car is going at 90 miles per hour, then guess what, it's going to take an hour to travel 90 miles. If the car is going half as fast then it takes twice as long. So at half the speed of 90 miles per hour (45 miles per hour) it's going to take two hours.

But what if the car isn't going at a constant speed, as most cars don't. Then you need to work out (or take a guess at) the average speed. The average speed for mostly freeway driving and a little bit of surface streets is most likely about 50 or 55 miles per hour, and for city driving could be about 15-25 miles per hour.

Since you are driving 90 miles, I am going to assume that you are not going to be doing city driving the whole way, and you are going to do a bit of freeway driving, so I will guess your average speed is going to be about 50 miles per hour.

At 50 miles per hour the journey takes 90 miles divided by 50 miles per hour, that is 1 4/5 hours. Four fifths (4/5) of an hour is 48 minutes, which gives a travel time of 1 hour 48 minutes at 50 miles per hour.

So that's because the question is in the math and algebra section. If you actually are travelling by car 90 miles, and you know where the start and end point are, the best way of getting a good estimate of your travel time is using Google Maps. Choose 'Get Directions', fill in the start and the end address and choose 'by car'. Look at the directions that are returned, and lo and behold, an estimate of the travel time.

Good luck travelling 90 miles in your car!!
