a man is climbing down from 250 feet high. he jumps 40 feet down and then descends at a rate of 30 feet per minute. how many minutes did it take him to reach the ground?

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
