Answer 1

Answer:

1 : 8

Step-by-step explanation:

A walks 7 1/2 miles in 2 hours

∴ A walks 15/2 miles in 2 hours

∴ in 1 hour A will walk 15/4 miles

∴ Speed of A = 15/4 mph

B walks 1/2 mile in 1 minute

∴ In 60 minutes ( 1 hour) B will walk 1/2 × 60 = 30 miles

∴ Speed of B = 30 mph

Ratio between their speeds​

Speed of A = 15/4  =  15/(4×30) = 1/8 or 1 : 8

Speed of B      30
