time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required = 
time required = 
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
The term sol is used by planetary astronomers to refer to the duration of a solar day on Mars.[7] A mean Martian solar day, or "sol", is 24 hours, 39 minutes, and 35.244 seconds.[6]
“Sol” is often used as a direct replacement for “Day” when concerning Mars. Mission duration for Mars missions is measured in Sols, so saying “Today is Sol xyz” would be normal, but I’m not sure if anyone would say “what a wonderful Sol tomorrow is going to be”.
