Question

Andy was told his dinner would be ready at 18:00. He left his house at 12:00 noon and traveled in his car at an average speed of 45mph to his mum’s house 300 miles away. What is the exact time Andy arrived for dinner?

Answer 1

Step-by-step explanation:

distance = speed ×time

time= distance/speed

time=300 miles/45 miles per hour

= 6.7 hours

6.7 hours= 6.7×60

=402 minutes

6 hours = 360 minutes

402-360=42 minutes

So 6.7 hours = 6 hours and 42 minutes

12+ 6 hr and 42 min= 18 hours and 42 minutes.

so Andy reached his mother's house at 18:42 or 6:42.
