When he exercises after work, marcus runs an average mile in 8.3 minutes. at this average, how many miles will he run after 36 minutes, rounded to the nearest tenth

Marcus will run an average of 4.3 miles after 36 minutes.

Step-by-step explanation:

Given:

Marcus runs an average mile in 8.3 minutes.

1 miles = 8.3 minutes

We need to find miles he ran at same average in 36 minutes.

How many miles = 36 minutes

Using Unitary Method we will find miles he run at 36 mins by multiplying 1 mile with 36 minutes and the dividing it with 8.3 minutes we get;

An Average mile run after 36 min =

Rounding to nearest tenth we get ≈ 4.3 miles.

Hence, Marcus will run an average of 4.3 miles after 36 minutes.

reduce the friction between its moving parts

step-by-step explanation:
