The unit of ratio is expressed as none. Ratio comprises of similar type of quantities so the units cancel out each other and thus there is no unit for a ratio. There is no unit for ratio. The numbers in the ratio will be of same unit - the unit can be meter or gram or litre or any such unit.
We are given:
The time t required to drive a certain distance varies inversely with the speed r.
According to the question t is inversely proportional to speed(r).
let us say distance (d) is constant of proportionality,
So the equation becomes,

Now from the question, we are given it takes 2 hours to drive the distance at 67 miles per hour, so plugging these in the above equation,

d=134 miles.
Now we have to find how long will it take to drive the same distance that is 134 miles at 55 miles per hour
so plugging the values, we have,

t=2.436
So the time taken will be around 2.5 hours.
Answer : It will take about 2.5 hours to drive the same distance at 55 miles per hour. Option C. About 2.5 hours.
The answer is "sometimes".
If A = 3 and B = 1 then, A > B and A-B < A+B
On the other hand, If A = 3 and B = -1, then A > B but A-B is not less than A+B.
