Miles hours and speed on a road trip step by step

What is speed?

Speed is the distance traveled per unit of time, often measured in miles per hour (mph).

Calculate speed: 150 miles in 3 hours.

Speed = Distance / Time = 150 miles / 3 hours = 50 mph.

True or false: Speed can be negative.

False, because speed is a scalar quantity that cannot be negative.

Difference between miles and kilometers.

Miles are used in the US, while kilometers are used in most other countries. 1 mile = 1.609 kilometers.

What is the formula to find time?

Time = Distance / Speed. This helps calculate how long a trip will take.

Fill in the blank: 60 mph means ____ miles in one hour.

60 miles in one hour.

What determines travel time?

Travel time is determined by distance and speed. Greater speed or shorter distances reduce time.

Calculate distance: 4 hours at 65 mph.

Distance = Speed x Time = 65 mph x 4 hours = 260 miles.

True or false: 30 mph is slower than 40 mph.

True, because 30 mph is less than 40 mph.

What is a practical use of miles per hour?

Miles per hour helps drivers understand how fast they are traveling and estimate arrival times.

Difference between average speed and instantaneous speed.

Average speed is total distance divided by total time. Instantaneous speed is the speed at a specific moment.

What was your speed if you drove 300 miles in 5 hours?

Speed = 300 miles / 5 hours = 60 mph.

Fill in the blank: To find time, divide distance by ____.

speed.

How can you estimate arrival time?

Add travel time to departure time. For example, leaving at 2 PM and traveling for 3 hours means arriving at 5 PM.

Calculate time: 240 miles at 80 mph.

Time = Distance / Speed = 240 miles / 80 mph = 3 hours.
