Question

Write four words of imagery​

Answer 1

Given her outbound journey took 5 hours to cover the 500 kilometres, we can calculate her average speed using Speed = Distance / Time

500 / 5 = 100 Kilometres Per Hour (KPH)

Which is approximately 60 Miles Per Hour for the imperial users out there!

But, since it only takes her 4 hours and 20 minutes to drive the 500 kilometre journey home, she must have travelled faster on average, and we can calculate the average exactly.

4 Hours and 20 Minutes is equivalent to 4 and 1/3 hours.

Therefore, using Speed = Distance / Time, we get:

500 / (4 + 1/3) = 115.38 KPH (to 2 decimal places)

= 115 KPH
