Question

interactive practice: express numbers using integer powers of 10
four students have a contest to see who can hop the farthest on one foot before losing their balance. this table shows the results.
which student wins the contest?
arturo
ella
jamilla
vinod

student	distance (km)
ella	$3 \times 10^{-4}$
jamilla	$1 \times 10^{-2}$
vinod	$9 \times 10^{-3}$

Explanation:

Step1: Convert to standard form

Arturo: $6 \times 10^{-2} = 0.06$ km
Ella: $3 \times 10^{-4} = 0.0003$ km
Jamilla: $1 \times 10^{-2} = 0.01$ km
Vinod: $9 \times 10^{-3} = 0.009$ km

Step2: Compare the distances

$0.06 > 0.01 > 0.009 > 0.0003$

Answer:

Arturo
