average speed = total distance/total time
The Attempt at a Solution
24. [/B]
The shortest road distance from Toronto City Hall to the Shaw festival theatre in Niagara-on-the-Lake is 131 km.
a)
First I will calculate the area of each rectangle using this formula: A = l x w
d = (40 km/h) (0.5 h)
= 20 km
d = (80 km/h) (1.0 h)
= 80 km
d = (60 km/h) (0.5 h)
= 30 km
Total distance travelled:
total d = 20 km + 80 km + 30 km
total d = 130 km
We already know that the shortest road distance from Toronto City Hall to the Shaw festival theatre is 131 km. In 2 hours, the transport has traveled a total of 130 km, meaning it has just about reached the festival theatre.
b)
Average speed of the truck = total distance / total time
= 130 km / 2.0 h
= 65 km/h
please verify if my answer is correct.
thank you :)
