A because centrifugal is to velocity to how slow or fast something is and centrifugal has expresssed as ac=v2 / r (1)<span />
Very simple,Its all about calculating distance using the formula:
D = V x T
where,
V is the speed or velocity
D is distance
T is the time
In the given problem,there are two parts.
Lets do the calculations for both parts separately:
Part 1) Before the rain
Time = 130/95
= 1.37 hours <span> </span>
<span>Time taken after the rain = Total time - time taken before the rain </span>
<span> = 3.34 hours - 1.37 hours
= 1.97 hours </span>
<span>Distance covered after the rain = 1.97 hours x 65 km/h
= 128 km</span>
Hence,
<span>a) The total distance covered = 130 + 128
= 258 km
</span><span>b) Average speed = Total distance/Total time
= 260/3.34
= 78 km/h </span>
