Question

Lin runs 2 3/4 miles in 2/5 of an hour. Tlyer runs 8 2/3 miles in 4/3 of an hour. How long does it take for each of them to run 10 miles

Answer 1

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
