Answer :
Answer:
Assuming he works at a constant rate, the daily rate Mark rakes lawns in the fall is 40% of the daily rate he mows lawns in the summer.
Step-by-step explanation:
Fall:
5 neighbours' lawns / 2.5 hours = 2 lawns per hour
Summer:
6 neighbours' lawns / 1.2 hours = 5 lawns per hour
2 x 100% / 5 = 40%
2 is 40% of 5
The percent of the daily rate should be 40%.
Given information:
One day in the fall, Mark raked the leaves on 5 neighbors’ lawns in 2.5 hr. One day in the summer, he mowed 6 neighbors’ lawns in 1.2 hr.
Calculation of the percent:
For fall
= 5 neighbours' lawns ÷ 2.5 hours = 2 lawns per hour
For Summer:
= 6 neighbours' lawns ÷ 1.2 hours = 5 lawns per hour
Now
[tex]= 2 \times 100\% \div 5[/tex]= 40%
