Question

Greta sets her watch 8 seconds behind, and it falls behind another 1 second every day. How many days has it been since Greta last set her watch if the watch is 49 seconds behind?

Answer 1

41 days

Explanation:

In order to solve this you can count or you can create an equation based on the formula y = mx + b.

By doing this you will be able to save yourself time

y - total number of seconds

x - total number of days

m - how much is increased per day

b - initial value

Based on this information you can create the equation below & solve

49 = x + 8

41 = x

Therefore the answer is 41 days
