How do you calculate the speed of two cars?

How do you calculate the speed of two cars?

To find this, we will subtract 4 from 52 and add 4 to 52. So, one car traveled 52 – 4 = 48 miles per hour, and the other traveled 52 + 4 = 56 miles per hour. 52 is the average speed of both cars together.

What is it called when multiple cars drive together?

(kɒnvɔɪ ) Word forms: convoys. countable noun [also in N] A convoy is a group of vehicles or ships traveling together.

How far must the faster car travel before it has a 15 minute lead on the slower car?

The faster car has to travel 89.375 miles to have 15-min lead.

How long will it take for car A to overtake car B?

Car A will overtake car B is about 7 seconds.

What additional time will it take for car B to catch up with car A?

The answer is very simple, since from the beginning car B is trailing car A, if car A stops after 70 miles and car B is traveling at 35 mph, it takes exactly 2 hours to catch-up.

How do you determine which fuel is more efficient?

Vehicle fuel efficiency This is known as Brake Specific Fuel Consumption (BSFC) and is determined by the rate of fuel consumption divided by the power produced, expressed as grams per kilowatt-hour and is a measure of the engines fuel efficiency.

What do you call it when cars follow each other?

Tailgating is the action of a driver driving behind another vehicle while not leaving sufficient distance to stop without causing a collision if the vehicle in front stops suddenly. When following heavy vehicles or in less than ideal conditions (e.g. low light or rain), a longer distance is recommended.

What are many cars called?

A group of cars is called FLEET.

How many miles does a car engine last?

How long an engine lasts requires a long list of variables to consider before a time frame or mileage can be given. I have seen engines last less than 40,000 miles and others that lasted more than 300,000 miles.

Is it possible for two cars to collide at 50 mph?

I imagine that either crash is very likely to be fatal at that speed. Addressing your new question, two cars crashing head-on each at 50 mph is essentially the same as one car going 100 mph and crashing into a stationary car, by the relativity principle.

How many miles will a 1916 car engine last?

Think of a 1916 car engine that is driven only 100 miles a year and put in storage after each use. After 100 years the engine will only have 10,000 miles on it. This motor may last a few hundred years before it would need rebuilding or replacement. This is why we use mileage to rate how long an engine will last.

Why do we use mileage to rate an engine?

This is why we use mileage to rate how long an engine will last. Most engines on the road today are designed to last well over 100,000 miles. An engine will last much longer if the engine is not abused in any way and all maintenance that the manufacturer recommends is done on or before it is due.
