wo mountain climbers start their climb at base camp, taking two different routes, one steeper than the other, and arrive at the peak at exactly the same time. Is it necessarily true that, at some point, both climbers increased in altitude at the same rate

It is necessarily true necessary to increase the altitude at same rate

Step-by-step explanation:

According to questions the time take by both the climbers is same where as their distance traveled and velocity is different

Let time taken to complete the journey for both the climbers= t

therefore t =  where

and is the distance traveled by climbers

and is the respective velocity of climbers

So, it is necessarily true necessary to increase the altitude at same rate as the time taken depends on the ratio of their respective altitude with velocity

i need a picure

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
