A slug travels the length of a log in 2 hours. If the slug's average speed is 1.5 cm / minute how long is the log

The length of the log is 180 cm

Explanation:

From the question given above, the following data were obtained:

Time = 2 hours

Speed = 1.5 cm/min

Distance =?

Next, we shall convert 2 hours to minutes. This can be obtained as follow:

1 h = 60 mins

Therefore,

2 h = 2 × 60

2 h = 120 mins

Finally, we shall determine the Lenght of the log. This can be obtained as follow:

Time = 120 mins

Speed = 1.5 cm/min

Distance =?

Speed = distance / time

15 = distance / 120

Cross multiply

Distance = 1.5 × 120

Distance = 180 cm

Therefore, the length of the log is 180 cm

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
