Question

Using the approximation of 5 miles = 8 km

How many km is 7.5 miles?

Answer 1

Step-by-step explanation:

$\frac{5}{8}$ = $\frac{7.5}{x}$

x*5 = 7.5*8

5x = 60  /:5

x = 12

7.5 miles = 12 km

Answer 2

Answer:

12 km

Step-by-step explanation:

5 miles = 8km

1 mile = 8/5 km

7.5 miles = 8/5 x 7.5 kms

= 12 kms

Therefore, 7.5 miles = 12km
