Question

While visiting Venice, Emily sees a sign that St. Mark's Square is 1,500 meters ahead. She wonders how long it will take her to get there if she walks at her usual pace of 15 minutes per mile. She decides to use the fact that 3 miles is approximately 5 kilometers to figure it out. In how many minutes should Emily expect to reach St. Mark's Square?

Answer 1

The answer is 13.50

Explanation:

Answer 2

Emily should expect to reach St Mark's market within 13.5 min

Explanation:

3 mile = 5 km

1 mile = 5/3 km

Emily can cover 1 mile in 15 min

i.e, 5/3 km in 15 min

i.e, (5 X 1000)/3 meters in 15 min

i.e, 5000/3 m in 15 min

1 m she will cover in 15/(5000/3) min

=( 15 X 3 )/5000 min

so, 1500 m she will cover = (15 X 3 X 1500)/5000

= 27/2 min = 13.5 min
