calculate speed,if john travels 220km for 2 hour 30 minutes ,your answer must be in km per hour
first convert the time given in hours.
2 hours & 30 min = 2.5 hours
then recall that speed is just distance traveled over time, or
v = d/t
substituting,
v = 220/2.5
v = 88 km/hr
hope this helps~ :)
To calculate speed, we need to use the formula:
Speed = Distance / Time
Given that John travels 220 km in 2 hours and 30 minutes, we first need to convert the time to decimal form. There are 60 minutes in an hour, so 30 minutes is equivalent to 30/60 = 0.5 hours.
Now, we can plug the values into the formula:
Speed = 220 km / 2.5 hours
Dividing 220 km by 2.5 hours gives us:
Speed = 88 km/h
Therefore, the speed at which John is traveling is 88 km/h.
