Question

20 POINTS

Answer 1

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

$Speed = \frac{distance}{time}=\frac{1158}{12}=96.5$ 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 $= \frac{484}{5}= 96.8$ 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.
