Answer:
The distance the tornado traveled was approximately 205 miles.
Step-by-step explanation:
The equation representing the relationship between the wind speed (in miles per hour) and the distance the tornado travels (in miles) is:
Compute the value of <em>d</em> for <em>s</em> = 280 as follows:
Thus, the distance the tornado traveled was approximately 205 miles.
Answer:
0.5hrs
Step-by-step explanation:
Let the speed downhill be ,
Speed uphill is . We are told than speed uphill is
the speed on flat ground. Therefore the speed on level ground will be
.
From this info, we can obtain the actual speed, on level ground as:
speed, distance and time have the relation so to obtain time to cover 45miles:
Hence it takes 0.5hrs to cover 45miles on flat ground.
