Answer:
Diameter is equal to 38 cm.
Step-by-step explanation:
We know that the circumference equals πd (where d is the diameter).
If we round the value of π to 3.14 then we will get...
πd = 119.32
(3.14)d = 119.32
d = 119.32 / 3.14
d = 38 cm
Therefore the diameter is equal to 38 cm
Hello,
Let's assume v=the normal bicycling speed with no wind
and t the same amount of time...
60=(v+2)*t (1)
48=(v-2)*t (2)
(1)/(2)==>60/48=(v+2)/(v-2)
==>5(v-2)=4(v+2)
==>5v-4v=8+10
==>v=18 (mi/h)
