Answer:
John's determination incorrect because he didn't give a unit rate which is miles per hour (mph).
The actual unit rate for his trip is v;
v = 70 miles ÷ 2 hours
v = 35 miles per hour
v = 35mph
Step-by-step explanation:
Given;
John travels 70 miles in 2 hours
John's determination incorrect because he didn't give a unit rate which is miles per hour (mph).
The actual unit rate for his trip is;
v = 70 miles ÷ 2 hours
v = 35 miles per hour
v = 35mph
Okay so the problem starts you off with the fraction (1/4). Sharing equally among 3 people would mean that you'd want to divide it by three so your equation would initially look like (1/4) / 3. Having two dividing signs is confusing so what you do is change the dividing into multiplying by the reciprocal of 3 = 1/3... This would make your expression (1/4) * (1/3) and when you simplify this you should get 1/12 as the answer.
1/4 = .25 of a mile
.25 of a mile * 4 laps = 1.0 mile
1 mile * 3 = 3 miles so 4 laps (1 mile) * 3 = 12 laps.
