Answer:
1.1 mph
Explanation:
Step one:
John swims a distance of 5/12 miles
time taken = 3/8 of an hour
Required
The speed with which John swims
Step two:
speed= distance/time
substituting we have
speed= 5/12/3/8
multiply the numerator by the inverse of the denominator
speed= 5/12*8/3
speed= 40/36
speed= 1.1 mph
