if it takes a man 12 minutes to travel 7 miles how fast was

if it takes a man 12 minutes to travel 7 miles how fast was he driving at one speed

Solution

From the problem we are given that he travels:
7 miles per 12 minutes
.
But, when we talk about speed we normally think in terms of \"miles per hour\" so just change the units of \"minutes\" to \"hours\":
7 miles/12 minutes * 60 minutes/1 hour = 420 miles/12 hours = 35 miles/ 1 hour
.
Answer: 35 mph
