Question

"1. You are driving a car in London and see that it says that you are going 50.45 km

(kilometers per hour).
a. Using the correct amount of significant figures, how fast are you going is
minute"

A) 0.8408 km/min
B) 3.027 km/min
C) 50.45 km/min
D) 30,270 km/min

Answer 1

To convert the speed from km/h to km/min, divide by 60 and round to three significant figures, resulting in 0.841 km/min.

Step-by-step explanation:

The question is asking to convert a speed from kilometers per hour to kilometers per minute using the correct amount of significant figures.

To do this, we will divide the given speed (50.45 km/h) by 60, since there are 60 minutes in an hour.

This calculation must be done with attention to the significant figures in the given data.

50.45 km/h ÷ 60 min/h = 0.8408 km/min.

When rounding to three significant figures, the result is 0.841 km/min.

Thus, the answer that has the appropriate number of significant figures and is reasonable is option A) 0.8408 km/min, which should be reported as 0.841 km/min when taking significant figures into account.
