Chapter 1 - Math 7 Review

Front

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

Back

Distance = Speed × Time

Front

If a car travels 60 miles in 1 hour, how far will it travel in 5 hours at the same speed?

Back

300 miles

Front

How do you convert miles per hour to feet per hour?

Back

Multiply the speed in miles per hour by 5280 (the number of feet in a mile).

Front

What is the relationship between gallons of gas and miles driven?

Back

The relationship can be expressed as a ratio: miles per gallon.

Front

If a vehicle uses 4 gallons of gas to drive 92 miles, what is the miles per gallon (MPG)?

Back

MPG = Total miles driven / Total gallons used = 92 miles / 4 gallons = 23 MPG.

Front

How can you find out how far a vehicle can travel with a different amount of gas?

Back

Use the miles per gallon (MPG) to calculate: Distance = MPG × Gallons.

Front

What is the speed of a dolphin in feet per hour if it swims at 40 miles per hour?

Back

40 miles/hour × 5280 feet/mile = 211,200 feet/hour.

Front

What is the unit of speed commonly used in the United States?

Back

Miles per hour (mph).

Front

How do you set up a proportion to solve for an unknown distance based on known distances and times?

Back

Set up a ratio of known distance to known time and set it equal to the unknown distance over the unknown time.

Front

What is the importance of understanding unit conversions in application-based math problems?

Back

Unit conversions are crucial for ensuring that measurements are compatible and calculations are accurate.
