Question

A car is traveling at 55 miles per hour. Use dimensional analysis to convert

Answer 1

The car's speed to feet per minute is  80.67ft per second.

What is speed?

• Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path.
• In other words, velocity is a vector, whereas speed is a scalar value.
• Speed is a way to gauge how rapidly something is happening, moving, or moving swiftly.
• The speed of a car being driven at 45 mph serves as an illustration. A person cleaning a room in 10 minutes is an illustration of speed. Speed can be compared to how swiftly a jaguar moves.

1 mile = 5280 feet 

so 55 miles = 55*5280 = 290,400ft 

there are 60 seconds in 1 minute and 60 minutes in 1 hour 

so 1 hour = 60*60 = 3600 seconds 

55mile/1hour = 290400ft/3600 seconds = 80.67ft per second
