A parachutist's speed during a free fall reaches 70 meters per second. What is this speed in feet per second? At this speed, how many feet will the parachutist fall during 20 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet

231 ft per sec, 4620 ft in 20 sec

Step-by-step explanation:

3.3ft*70=231ft per sec.

231ft*20=4620ft in 20 sec

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right
