Problema Solution
Amanda and her friends made a snowman that was 4 feet tall. If he melted at the rate of 3 inches for every 40 minutes, how long would it take to completely melt the snowman
Answer provided by our tutors
1 foot = 12 inches
4 feet = 4*12 = 48 inches
the rate of melting is 3 inches in 40 min and lets assume it takes x minutes for the 48 inches to melt
since the rate is constant we can write
3 : 40 = 48 : x
by solving we find
x = 640 min = 10 hours 40 min

it takes 10 hours and 40 min for the snowman to melt.
