A couple walking in the park strolls 1.5 km in 60 min. What is the couple’s average speed in m/h?

1,500m/h

Explanation:

the information that we have is:

distance traveled:

to convert this quantity to meters we remember that 1km = 1,000m

so the distance in meters is:

and we also know the time

time: , and since 60min = 1hour, the time in hours is:

now we use the formula for the average speed:

and we sustitute the known values (since we want the answer to be in m/h we substitute the distance in meters (m) and the time in hours(h)):

the speed of the couple in m/h is: 1,500m/h
