Question

An experiment was performed to find the average speed of a grasshopper. The average speed has been plotted on the number line as marked by the arrow,

Hi
10 feet/sec
11 feet/sec
What is the speed of the grasshopper in feet per second?
B
33
C

Answer 1

10.375ft/s

Explanation:

We need to read the number from the plot. The range from 10 to 11 is divided into 8 segments, so each segment is (11-10)/8=0.125

The answer is at 10 + 3 segments, so 10 + 3*0.125 = 10.375
