Given:
Jai ran three-fourths of a half-mile.
His pace was 12 miles an hour until the point he dropped out of the race.
To find:
About how many minutes did he run approximately?
Solution:
From given, we have,
Jai ran ran 12 mph.
1 hour = 12 miles
we know that, 1 hr = 60 minutes.
Therefore, we have,
60 minutes / 12 miles = 5 min/mile
For 1 mile - 5 minutes.
As Jai ran three-fourths of a half-mile,
For 1/2 mile - 5/2 minutes
∴ (5/2) mins/mile × (3/4) miles = 15/8
= 1.875 ≈ 2
About 2 minutes approximately Jai ran .
