Question

Jai ran three-fourths of a half-mile and dropped out of the 800-meter race. His pace was 12 miles an hour until the point he dropped out of the race. About how
many minutes did he run approximately?
A) 1 minute B) 2 minutes C) 3 minutes D) 4 minutes

Answer 1

Answer:

approximately 2 minutes

Step-by-step explanation:

First step, ignore the 800 meters. That is extra information that adds no value to your calculations.

If he ran 12 mph, calculate how long it would take to run 1 mile. (In minutes, because the final answer will be in minutes)

1 hr = 60 minutes. So, (60 minutes)/(12 miles) = 5min/mile

It would take 5 minutes to run 1 mile. Jai did not run a full mile, he ran part of half of a mile.

It would take him 5 x (1/2) or 2.5 minutes to run half of a mile,

and (5min/2miles) x (3miles/4) = 15/8 = 1.875 = about 2 minutes
