You could use a thermometer on a pets fur if it was outside or measure the amount of air in a ball since air is heated it expands there for making the ball have more air? it’s a long shot but i would just go for the first idea to be honest
Answer:
Step-by-step explanation:
first runs n+1 laps
and second runs n laps in the same time.
so (n+1)8=10n
10n=8n+8
10n-8n=8
2n=8
n=8/2=4
one lap=1 mile
4 laps=4 miles
4+1=5 laps=5 miles.
first runs 5 miles whereas second runs=4 miles.
