The speed of Albert and Tanisha can be calculated using the graph by determining the slope of the line that describes their motion respectively.
We can simply take two points on each lline in the graph to represent the speed of the Albert and Tanisha.
Notice that Albert covered 1 mile in 10 minutes and 2 miles in 20 minutes and so on. Thus
Albert's speed is:
Speed = 1 mi / 10 min = 0.1 mi/min -- 0.1 mi/min x 60 min / hr = 6 miles per hour
Tanashi, on the other hand, covered 1 mile in 20 minutes and 2 miles in 40 min and so on.. Thus Tanashi's speed is:
Speed = 1 mi /20 min = 0.05 mi/min -- 0.05 mi/min x 60 min / hr = 3 miles per hour
Albert's Speed = 6 miles per hour
Tanashi's Speed = 3 miles per hour
Answer:
ALBERT IS RUNNING 3 mi/ hr FASTER THAN TANASHI
