What is a map scale?

Back

A map scale is a ratio that compares a distance on the map to the actual distance it represents in real life.

Front

If a map has a scale of 1 inch to 5 miles, how do you calculate the real distance between two points?

Back

Multiply the distance on the map (in inches) by the scale factor (5 miles per inch).

Front

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

Back

Distance = Speed × Time.

Front

If a car travels at a speed of 60 miles per hour for 3 hours, how far does it travel?

Back

180 miles (60 mph × 3 hours = 180 miles).

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials.

Front

In an experiment where a coin is flipped 10 times and lands on heads 7 times, what is the experimental probability of getting heads?

Back

Front

How do you calculate the speed of an object?

Back

Speed = Distance ÷ Time.

Front

If a train covers 150 miles in 2.5 hours, what is its speed?

Back

The speed of the train is 75 mph (150 miles ÷ 2.5 hours = 75 mph).

Front

What is the formula for the area of a rectangle?

Back

Area = Length × Width.

Front

If a rectangle has a length of 8 cm and a width of 4 cm, what is its area?

Back

The area is 32 cm² (8 cm × 4 cm = 32 cm²).
