Hoshi walks 10 meters in 3 seconds
What is her walking rate?
At this rate, how long does it take for her to walk 100 Meters?
Suppose she walks this same rate for 50 seconds. How far does she walk?
What is an equation that represents the distance d that Hoshi walks in t seconds?
Please help me with these questions I am clueless.

distance = rate * time
so
rate = distance / time
1) distance = 10 meters
time = 3 seconds
rate = 10 meters / 3 seconds = 3.33 . . . meters/second
2) distance = 100 meters
rate = 3.33 meters/second
time = 100 meters / (3.33 meters/seconds) = 33.3 seconds
3) time = 50 seconds
rate = 3.33 . . . meters/second
distance = 50 seconds * 3.33 meters/second = 166.5 meters
4) Let d be the distance Hoshi walks in t seconds.
d = 3.33t

If Hoshi walks 10 meters in 3 seconds, then her walking rate per second is 10 divided by 3...
10/3 = 3.333333333333333
To find out how long to walk 100 meters, divide the distance by her walking rate...
100/3.333333333333333333= 30 seconds...
To find out how far she walk in 50 seconds, you can use the equation
D=V*T
or
Distance = Velocity * Time
D= (3.3333333 meters/second)*(50 seconds)
D=166.666666666 meters...

If she walks 10 meters in 3 seconds, then she walks (10/3) meters per second, so your equation would then be:
d = 10t / 3.
To walk 100 meters:
100 = 10t / 3.
300 = 10t.
t = 30 seconds.
If she walked 50 seconds:
d = 10 * 50 / 3.
d = 500 / 3, or 166 2/3 meters.

10/3 =x/60. 60x10= 600 divided by 3 = 200.
she walks 200 m. per minute.
100 meters in 30 seconds.
and about 167 meters in 50 seconds.

10 meters in three seconds is equal to (10 * 20) or 200 meters in one minute. You multiply it by 20 because 60 (seconds in a minute) divided by 3 is 20.
distance = rate * time

3 and 1/3 meters per second.
it will take her 30 seconds to walk 100 meters
in 50 seconds she will walk about 160 meters

3 meters per seconds
30 seconds
500 meters
d = rate x time or d = r/t
