Ans(a):
Given that total distance = 1158 km
Estimated time of drive = 12
now question says to distance that can be driven in 1 hour.
Indirectly it is asking for his speed.
So we can use formula of speed
[tex] Speed = \frac{distance}{time}=\frac{1158}{12}=96.5 [/tex] km per hour.
Hence he will drive approx 96.5 km in 1 hour.
Ans(b):
Actual driven distance = 484 km
Actual time taken = 5 hours
Then actual speed [tex] = \frac{484}{5}= 96.8 [/tex] km per hour
Comparing speeds in both parts, we see that actual speed 96.8 km/hour is more than the expected speed 96.5 km/hour.
Hence he will reach at his destination on schedule or before the expected time.
