Question

Max travels to see his brother's family by car. He drives 216 miles in 4 hours. What is his rate in miles per house? Use a double number line to show your work.

Answer 1

54 miles/hour

Explanation:

His rate in miles per hour will be also his speed: to calculate the speed, we just need to divide the total number of miles travelled by the total number of hours, so we will have the average speed in the course:

Speed = 216 miles / 4 hours = 54 miles/hour

So the rate Max travelled is 54 miles per hour.

Answer 2

The rate at which Max travels with the car is 54 miles per hour (54 mph)

Explanation:

Speed is simply a measure of the distance that something or someone covers in a specific period or time. Some others describe speed as the measure of distance that is covered in each unit of time.

In this case, we are told that Max uses his car/vehicle to cover or travel a distance of two hundred and sixteen miles (216 miles) in about four hours(4 hours). In order to calculate Max's average speed or the distance that he covers with his car in one hour, we will simply divide the distance he has covered already by the time it took him to cover the distance using the car. That is:

4 hours ---------- 216 Miles

1 hour ----------- ? miles

1/4 × 216

= 54 miles per hour

Therefore,the car's average speed or the rate at which he travels with us car is 54 miles per hour (54 mph).
