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: [tex]d=1.5km[/tex]
to convert this quantity to meters we remember that 1km = 1,000m
so the distance in meters is:
[tex]d=1.5km(1000m/1km)\\d=1.5(1000)\\d=1,500m[/tex]
and we also know the time
time: [tex]t=60min[/tex], and since 60min = 1hour, the time in hours is:
[tex]t=1h[/tex]
now we use the formula for the average speed:
[tex]v=\frac{d}{t}[/tex]
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)):
[tex]v=\frac{1,500m}{1h}\\ v=1,500m/h[/tex]
the speed of the couple in m/h is: 1,500m/h
