Answer:
The speed of the bicycle is 3 miles per hour
Step-by-step explanation:
Step 1
Determine the distance covered, and the time the bicycle takes as shown;
distance=3/4 miles
time=1/4 hours
Step 2
Derive the expression for the speed of the bicycle as follows;
S=D/t
where;
S=speed in miles per hour
D=distance traveled in miles
t=time taken in hours
In our case;
D=3/4 miles
t=1/4 hour
replacing;
S=(3/4)÷(1/4)=(3/4)×(4/1)=3 miles per hour
The speed of the bicycle is 3 miles per hour
