HW #40

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

If two objects move in opposite directions, how do you calculate the distance between them after a certain time?

Back

Add the distances traveled by both objects.

Front

What is the average speed of an object?

Back

Average Speed = Total Distance / Total Time

Front

How do you convert hours and minutes into hours for calculations?

Back

Convert minutes to hours by dividing by 60 and add to the hours.

Front

If a car travels at 50 mph for 2 hours, how far does it travel?

Back

Distance = 50 mph × 2 hours = 100 miles.

Front

A passenger plane flies at 217 km/h. How far does it travel in 4 hours?

Back

Distance = 217 km/h × 4 hours = 868 km.

Front

If one car travels south at 60 mph for 1 hour and 15 minutes, how far does it travel?

Back

Distance = 60 mph × (1 + 15/60) hours = 75 miles.

Front

What is the relationship between speed, distance, and time?

Back

Speed = Distance / Time; Time = Distance / Speed.

Front

If Jill drives at 80 km/h and they are 450 km apart after 3 hours, how do you find Maria's speed?

Back

Maria's speed = (Total distance - Jill's distance) / Time.

Front

How do you find the time it takes for one object to catch up to another?

Back

Set the distance equations equal to each other and solve for time.
