Mark leaves uncc at 1: 00 p. m. going 50mph and alex leaves uncc at 3: 00 p. m. going 70mph on the same highway in the same direction. at what time does alex catch up with mark?

Mark has a 100-mile head start (2 hours at 50 miles per hour). Alex is closing at the rate of 70 - 50 = 20 miles per hour. It will take him

... (100 mi)/(20 mi/h) = 5 h

to catch up.

Alex catches up with Mark at 8:00 pm.

They will meet up 350 miles from uncc.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
