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
Answer:
1 hour = 7/18 of the distance between two ports
Step-by-step explanation:
Given that:
In 3/7 hours distance traveled is 1/6
For finding distance in one hour, divide both sides by 7/3 so that 3/7 would be cancelled out:
3/7 * 7/3 hours = 1/6 * 7/3 distance
By simplifying:
1 hour = 7/18 of the distance between two ports
This means that in one hour 7/18 of the distance is covered between two ports.
