It took Peter 3 hours to drive to his friend's home in Connecticut. He drove at an average speed of 54 mph. How much time will the way back take if Peter drives at an average speed of 60 mph?
To find the time it will take for the way back, we can use the formula: time = distance / speed.
Since the distance to his friend's home in Connecticut remains the same on the way back, we don't need to calculate it again.
We know that the distance is the same, so we can use the same distance for the way back as well.
The time on the way back can be calculated as follows:
time = distance / speed
time = distance / (60 mph)
Given that the time on the way to his friend's home is 3 hours, the distance can be calculated as follows:
distance = speed * time
distance = 54 mph * 3 hours
distance = 162 miles
Substituting the distance into the formula above, we get:
time = 162 miles / (60 mph)
Calculating this, we find:
time = 2.7 hours
Therefore, the way back will take approximately 2.7 hours.
