Sal was tired of waiting for amir to show up at their meeting place, so he started running at an average speed of 4.5 mph without him. ten minutes later, amir still had 0.25 of a mile to go before he reached the meeting place, but sal was 0.75 of a mile beyond it. if amir is running at a faster pace, 6.7 mph, to the nearest hundredth of an hour, after how much time will amir catch up to sal? 0.04 hours 0.09 hours 0.23 hours 0.45 hours

a=-.25+6.7t, s=.75+4.5t  when Amir catches up a=s so:

-.25+6.7t=.75+4.5t  (add .25 to both sides)

6.7t=1+4.5t (subtract 4.5t from both sides)

2.2t=1  (divide both sides by 2.2)

t=10/22 hr

t≈0.45 hr (to nearest hundredth)

the answer is 0.45

0.45 hours

Explanation:

because i just took the quiz

the boy's acceleration toward the girl is 2.08 m/s^2.

explanation:

according the newton's third law, the force causing the girl accelerate towards the boy will be me with equal counter-force causing the boy to accelerate towards the girl. these forces will be of equal magnitude and allows us to determine the boy's acceleration:

the boy's acceleration toward the girl is 2.08 m/s^2.

noo because no animal can leave it's mother land and freedom even we can't leave some days in a single room by leaving home it is wrong but needed to protect them
