Answer:
562 miles per hour.
Explanation:
As given in the question, the formula for the maximum speed on a curved road is
Given value of feet
So the maximum safe speed will be
miles per hour.
Rounding off to the nearest whole number we get the maximum safe speed at the curved road is 562 miles per hour.
Answer:
The average speed would be 279.167 meters per second.
Explanation:
Speed is the magnitude that expresses the variation in position of an object and as a function of time. In other words, speed is defined as the relationship established between the distance traveled and the time elapsed in the movement of a mobile.
Speed can be calculated using the following expression:
In this case:
- distance= 7,035 km
- time= 7 hours
Since the required unit of speed is meter per second, then you convert from km to meters for the case of distance, and from hours to seconds for the case of time. So:
- distance= 7,035 km= 7,035,000 m (being 1 km= 1,000 m)
- time= 7 hours= 420 minutes= 25,200 seconds (being 1 hour=60 minutes and 1 minute=60 seconds)
Replacing in the definition of speed:
Solving:
Then, <u><em>the average speed would be 279.167 meters per second.</em></u>
