Answer:

c) 73.0: three significant figures.

d. 532.5: four significant figures.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to write each number by knowing we move the decimal places to the right as much as the exponent is, and also, we count every figure, even zeros, because they are to the right of the first nonzero digit:

a) 320: two significant figures because the rightmost zero is not preceded o followed by a decimal place.

b) 2,366: four significant figures.

c) 73.0: three significant figures, because the zero is followed by the decimal place.

d. 532.5: four significant figures.

Regards!

<h3>Further explanation</h3>

Given

d1 = 2 km

t1 = 9 min

d2 = 1.5 km

t2 = 10 min

Required

The average speed

Solution

Average speed = total distance : total time

total distance :

= d1+d2

= 2+1.5

=3.5 km

total time :

= t1+t2

= 9 min + 10 min

= 19 min

Average speed :

= 3.5 km : 19 min

= 0.184 km/min

= 3.07 m/s
