A person jogs 1/7 mile in 1/42 hour.
The person's speed is ____ miles per hour.
(1/7 mi) / (1/42 hr) = 42/7 mi/hr = 6 mi/hr
To find the person's speed in miles per hour, we need to divide the distance (1/7 mile) by the time (1/42 hour).
So, the person's speed is (1/7 mile) ÷ (1/42 hour).
We can simplify this by multiplying both the numerator and denominator by the reciprocal of the denominator, which is 42/1:
(1/7) ÷ (1/42) = (1/7) × (42/1)
Multiplying across gives us:
= (1 × 42) / (7 × 1)
= 42/7
= 6
Therefore, the person's speed is 6 miles per hour.
To find the person's speed in miles per hour, we need to divide the distance jogged by the time taken.
Given that the person jogs 1/7 mile in 1/42 hour, we can divide 1/7 by 1/42:
(1/7) / (1/42) = (1/7) * (42/1) = 42/7 = 6 miles per hour.
Therefore, the person's speed is 6 miles per hour.
