    Answer:

    0.932 m/h

    Explanation:

    Parameters given:

    Distance walked by couple, D = 1.5 km

    Time spent in walking, t = 60 min

    To solve this we simply apply the formula for average peed:

    Average Speed = total distance / total time taken

    The question asks specifically to put the answer in miles per hour (m/h), hence, we need to convert the distance to miles and the time to hours:

    Distance in miles:

    1 km = 0.622 miles

    1.5 km = 1.5 * 0.622 = 0.932 miles

    Time in hours = 60 / 60 = 1 hour

    Hence, the speed is:

    Speed = 0.932 / 1 = 0.932 m/h

    The average speed of the couple is 0.932 m/h

    Answer:

    1,500m/h

    Explanation:

    the information that we have is:

    distance traveled: d=1.5km

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

    so the distance in meters is:

    d=1.5km(1000m/1km)\\d=1.5(1000)\\d=1,500m

    and we also know the time

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

    t=1h

    now we use the formula for the average speed:

    v=\frac{d}{t}

    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)):

    v=\frac{1,500m}{1h}\\ v=1,500m/h

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