20/42*60 miles/hr or 1200/42 or 200/7 = 28and 4/7 mile per hour

S = D/T
S = 20/42
S = (10/21)
S = about 0.476190 mpm with 476190 repeatinig
or
S = 20/(42/60)
S = (20/1)/(7/10)
S = (20/1)*(10/7)
S = (200/7)
S = about 28.571428 mph with .571428 repeating

Speed = distance / time
= 20 / 42
= 0.476190476190 Miles/minutes
Ha ha ha very simple

Your time is 42 minutes.
Your distance 20 miles.
Speed = Distance / Time
Your speed is .476 miles per minute

CONVERT 42 MIN TO HOURS THEN
42MIN = 0.7 HRS
AS SPEED = DISTANCE/TIME
THEN SPEED = 20MILES/0.7HR
SO YOUR SPEED = 28.571MI/HR

Divide 20 by 42 then multiply by 60.
The first part gives you how far you have traveled in 1 minute, the second in an hour.
The answer is 28.57 MPH

42 min 20 miles
01 min 20/42 m
60 min 20x60/42 = 200/7 miles per hour
In science (physics) speed n velocity is different

28.5714 miles per hour or 28.57 miles per hour
20 miles : 42 minutes = X : 60 minutes(1hour)
(42minutes)X = (20miles)(60minutes)
divide both sides by 42minutes
X = 1200miles over 42 min
X = 28.57 miles

s = v/t
42 minutes = 42/60 hours = 0.7 hours
s = 20 mi / 0.7 hours
s = 28.57 mph

42 minutes = 0.7 hour
20 mi / 0.7 hr = 28.57 mph

42 [min] * (1 [hour] / 60 [min])
=42/60 [hour] * [min/min]
=.7 hours
20 [miles] / .7 [hour]
=28.6 mph

d = rt
20 = r* 42/60
1200 = 42r
r=28.571....
