Lea reads 60 pages in 2 hours how long will is take him to read 17 pages at the same rate

34 minutes

Step-by-step explanation:

Method I - set up a proportion

t/17 = 2/60

multiply both sides by 17

t = 2/60 * 17

t = 0.5666666667 hr

in minutes

0.5666666667 hr * 60min/hr

34 minutes

Method II - rate

2 hours = 120 minutes

r = 120min / 60pages

r = 2 min / page

for 17 pages

t = 1 min / page * 17 pages

t = 34 minutes

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
