Answer:speed of slower cyclist is 5 mph
Explanation:
Given
Distance between two cyclist is 50 miles
One cycle is 4 times fast as other
Speed of slower cyclist is r miles per hour
speed of faster cyclist is 4 r
they meet after t=2 hr
Distance traveled by fast cyclist is 
Distance traveled by slower cyclist is 






speed of slower cyclist is 5 miles per hour

3,89,988 cm/min is the linear velocity
Given,
Diameter of CD = 12 cm
So, Radius of CD = 6 cm
CD is spinning at 10350 rev/min
Firstly , convert rev/min into rad/min
1 rev = 2π radians
10350 rev/min = 10350 × 2π
= 64998 rad/min
Formula used,
where,
is the Linear velocity
is the radius
is the angular velocity
= 6 cm × 64998rad/min
= 3,89,988 cm/min
Thus, linear velocity for any edge point of a 12-cm-diameter CD (compact disc) spinning at 10,350 rev/min is 389988 cm/min.

milligrams
Explanation:
The best unit to measure the mass of a grain of salt is the milligram.
This is about; a thousandth of a gram.
A grain of salt is a very small particle size that can still be visible with the eye.
It has a very low and small mass.
For substances like this, we use the milligram:
1000milligram = 1g
