Question

You have to deliver medicines 1 mile away. In order to do that, you have to which drone to use depending on the size of the blade in the drone. The equation that gives the relationship between the size of the blade (b) in inches and speed (miles/hour) is as follows: Speed = 50-2b In order to deliver the medicine in time, the drone must travel faster than 37 miles/hour. Check the box underneath the blade that you would like to use. Then write the speed of the drone using this blade.

Answer 1

From the information given,

The equation representing the relationship between the size of the blade (b) in inches and speed (miles/hour) is given as

Speed = 50-2b

Also, the required drone must travel faster than 37 miles/hour.

For the small blade, b = 4 inches

speed = 50 - 2 * 4 = 50 - 8

speed = 42 miles/hour

For the medium blade, b = 6 inches

speed = 50 - 2 * 6 = 50 - 12

speed = 38 miles per hour

For the large blade, b = 8

speed = 50 - 2 * 8 = 50 - 16

speed = 34 miles per hour

Since the speed of the drone with small blade is greater than 37 miles per hour and it is the greatest among the three drones,

The speed of the drone will be 42 miles per hour
