Question

Martina runs 7 miles in 50 mins at the same rate how many miles will she run in 75 mins

Answer 1

Martina runs 10.5 miles in 75 minutes

Solution:

Given that,

Martina runs 7 miles in 50 minutes

Therefore, miles ran in 1 minute is:

$Miles\ ran\ in\ 1\ minute = \frac{7}{50}\ miles$

At the same rate how many miles will she run in 75 mins

Thus, to find the miles ran in 75 minutes:

$Miles\ ran\ in\ 75\ minute = \frac{7}{50}\ \times 75\\\\Miles\ ran\ in\ 75\ minute = 0.14 \times 75\\\\Miles\ ran\ in\ 75\ minute = 10.5$

Thus she runs 10.5 miles in 75 minutes
