Answer:
600
Step-by-step explanation:
The circumference of a tire is the distance around it. The distance around these tires is 1 m. Since the tires revolve 15 times per second, this means every second the tires travel 15 m. This means that in 40 seconds, the tires travel15(40) = 600 m.
15 x 40 = 600
Perimeter = 2L + 2W
42= 2L + 2(8)
26 = 2L
13 = L
