John is driving to his office to attend a meeting. In the first 10 minutes, he covers a distance of 1 mile every minute. Then he stops at a local restaurant for 15 minutes to have breakfast. After that, he covers a distance of 0.5 miles every minute in the next 10 minutes to reach his office.

The total distance cover by John is 15 min to reach his office.

Step-by-step explanation:

Given as;

In the first 10 minutes, the distance cover is 1 miles every minutes

So, for 10 minutes, total distance cover by John = 10 * 1 = 10 miles

Again,

John cover distance of 0.5 miles for every minutes, he travel for next 10 min

So, for next 10 min, total distance cover by John = 10 * 0.5 = 5 miles

So, The total distance cover by john = 10 miles + 5 miles = 15 miles

Hence The total distance cover by John is 15 min to reach his office. Answer
