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

because i just took the quiz

Anne Frank and her family spent two years hiding in a secret attic apartment behind the office of a family-owned business in Amsterdam.
