Answer 1

It will take her 24 minutes to reach her friend's house

It will take her 12 minutes to reach her friend's house

Explanation:

Meredith lives 24 blocks from her friend's house

let the number of minutes to get to 24 blocks = y

1 block = 1 minutes

24blocks = y

Cross multiply:

y(1 ) = 24 (1)

y = 24 minutes

It will take her 24 minutes to reach her friend's house

if she travels 2 blocks every minute:

let the number of minutes to get to 24 blocks = y

2 blocks = 1 minutes

24 blocks = y

cross multiply:

2(y) = 24 (1)

2y = 24

y = 24/2

y = 12 minutes

It will take her 12 minutes to reach her friend's house

for 24 min, speed = 24blocks/24minutes = 1 block/min

for 12 minutes , speed = 24blocks/12minutes = 2 blocks/min

speed =number of blocks/time

time = number of blocks/speed

for 3: at 3 blocks/minute, time = 24/3 = 8 minutes

for 4: at 4 blocks/minute, time = 24/4 = 6 minutes

for 8: at 8 blocks/minute, time = 24/8 = 3 minutes

for 10: at 10 blocks/minute, time = 24/10 = 2.4 minutes
