A man set out at 12.15pm to visit his son at school 175 km away.If he travels at an average speed of 75km/hour,when does he arrive at the school

Answer 1

To find out when the man arrives at the school, we need to determine the total time it takes for him to travel 175 km at an average speed of 75 km/h.

The formula to calculate the time taken for a journey is:

Time = Distance / Speed

Given that the man is traveling at an average speed of 75 km/h and the distance to the school is 175 km, we can calculate the time taken as follows:

Time = 175 km / 75 km/hour

Time = 2.33 hours

However, since the man set out at 12.15 pm, we need to add the travel time to this starting time to determine the arrival time.

Since 2.33 hours is equivalent to 2 hours and 20 minutes (0.33 × 60), we can add this time to the initial departure time of 12.15 pm.

Therefore, the man will arrive at the school at 2.35 pm (12.15 pm + 2 hours and 20 minutes).
