Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h
