Da Ming walks from his school to his house at a speed of 5km/h.he takes 20 minutes to reach home.what is the distance between his school&his house? Convert the time from minutes to hour and correct to 2 decimal places
20 min = 20/60 hrs = 1/3 hr
distance = time x speed
= (1/3)(5) = 5/3 or appr 1.67 km
To find the distance between Da Ming's school and his house, we need to convert the time from minutes to hours.
Given:
Speed = 5 km/h
Time = 20 minutes
Step 1: Convert minutes to hours
Since there are 60 minutes in an hour, divide the given time by 60 to convert it to hours:
20 minutes / 60 = 0.33 hours (rounded to 2 decimal places)
Step 2: Calculate the distance using the formula:
Distance = Speed * Time
Distance = 5 km/h * 0.33 hours
Distance = 1.65 km
Therefore, the distance between Da Ming's school and his house is 1.65 kilometers.
