Answer:
Average Speed = 6.37 m/s
Explanation:
The average speed is simply given by the following formula:
Average Speed = Total Distance Traveled/Total Time Spent
here,
Total Time Spent = 1.1 min + 1.5 min = (2.6 min)(60 s/min) = 156 s
Now, for total distance, we have to calculate the distance traveled on tortoise and distance traveled while flying, separately. Therefore,
Distance Traveled on Tortoise = (Time spent on Tortoise)(Speed of Tortoise)
Distance Traveled on Tortoise = (1.1 min)(60 s/min)(0.06 m/s) = 3.96 m
Similarly,
Flying Distance = (Flying Time)(Flying Speed) = (1.5 min)(60 s/min)(11 m/s)
Flying Distance = 990 m
Since, total distance is the sum of both distances, therefore,
Total Distance = 3.96 m + 990 m = 993.96 m
Now, using the values in equation of average speed, we get:
Average Speed = 993.96 m/156 s
<u>Average Speed = 6.37 m/s</u>
