Answer:
Total distance = 22.5 kilometers
Step-by-step explanation:
Let the first distance be A.
Let the second distance be B
Given the following data;
Speed A = 30km/h
Time A = 15 minutes to hours = 15/60 = 0.25 hour
Speed B = 60km/h
Time B = 15 minutes to hours = 15/60 = 0.25 hour
Now, to find the respective distance traveled;
Distance A = speed A * time A
Distance A = 30 * 0.25
Distance A = 7.5 km
Distance B = speed B * time B
Distance B = 60 * 0.25
Distance B = 15 km
Next, we calculate the total distance traveled;
Total distance = Distance A + distance B
Total distance = 7.5 + 15
Total distance = 22.5 kilometers.
Therefore, the total distance covered by the object is 22.5 kilometers.
