Calculating Train Distance with Significant Figures

What distance does the train cover expressed to the correct number of significant figures?

A train travels at a constant speed of 60.4 mi/h for 101.5 min. How far does the train travel with the correct number of significant figures?

Answer:

The distance covered by the train is approximately 102 mi (rounded to three significant figures).

When a train travels at a constant speed of 60.4 mi/h for 101.5 min, the distance covered by the train is approximately 102 mi, rounded to three significant figures.

Calculating the Distance:

The formula to calculate distance is: Distance = Speed x Time

Given:- Speed = 60.4 mi/h (with 3 significant figures)- Time = 101.5 min (with 4 significant figures)

Before calculation, ensure that the units are consistent. Convert the time from minutes to hours:

101.5 min = 101.5 min / 60 min/h = 1.69166667 h

Now, calculate the distance:

Distance = 60.4 mi/h x 1.69166667 h = 102.23 mi

Expressing the distance to the correct number of significant figures, round it to match the least precise value, which is 3 (from the speed). So, the distance covered by the train is approximately 102 mi.
