A horse galloped a mile in 2 min 35s. What was its average speed in km/h?

To find the average speed in km/h, we need to convert the distance traveled to kilometers and the time taken to hours.

1 mile is approximately 1.60934 kilometers.

First, let's convert the distance:
Distance in kilometers = 1 mile × 1.60934 = 1.60934 kilometers

Next, let's convert the time:
Time in hours = (2 minutes + 35 seconds) ÷ 60 minutes per hour
= (2 + 35/60) ÷ 60 hours
= 2.5833 ÷ 60 hours
≈ 0.0431 hours

Finally, we can calculate the average speed:
Average speed = Distance ÷ Time
= 1.60934 kilometers ÷ 0.0431 hours
≈ 37.32 km/h

Therefore, the average speed of the horse is approximately 37.32 km/h.

To calculate the average speed of the horse, you need to convert the distance from miles to kilometers and the time from minutes to hours. Here's how you can do it:

1. Convert the distance from miles to kilometers:
- 1 mile is approximately equal to 1.60934 kilometers.
- Multiply the given distance (1 mile) by the conversion factor (1.60934 km/mile) to get the distance in kilometers.
- In this case, 1 mile * 1.60934 km/mile = 1.60934 kilometers.

2. Convert the time from minutes to hours:
- There are 60 minutes in an hour.
- Divide the given time (2 minutes 35 seconds) by 60 to get the time in hours.
- In this case, (2 minutes + 35 seconds/60) / 60 = 2.5833 hours (rounded to four decimal places).

3. Calculate the average speed by dividing the distance (in kilometers) by the time (in hours):
- Divide the distance (1.60934 kilometers) by the time (2.5833 hours) to find the average speed in kilometers per hour.
- In this case, 1.60934 km / 2.5833 hours ≈ 0.6224 km/h (rounded to four decimal places).

Therefore, the average speed of the horse is approximately 0.6224 km/h.

change time to seconds. Then seconds to hours.

change mile to km.

avgspeed=distance/time=1mile/(2min35sec) or
= 1mile/(2min+35sec)*1min/60sec=
=1mile/(2*60+35)sec*3600sec/hr

=1mile*1.609 Km/mile

= 1.609km/155sec*3600sec/hr
=about less than 40km/hr.
