these are the only 2 questions i don't get:
-how long would it take for a car to travel a distance of 200 km if it is travaling at a velocity of 55 km/hr?
is the answer 4hrs and 3 min.?
-an an carries food at a speed of 1 cm/s.how long will it take the ant to carry a cookie crumb from the kitchen table to the ant hill,a distance of 50m? express ur answer in seconds,minutes,andhours
i didn't get that one at all
Thank You very much!!! :)
Sure! Let's start with the first question:
Question: How long would it take for a car to travel a distance of 200 km if it is traveling at a velocity of 55 km/hr?
To find the time it takes for the car to travel a distance, you can use the formula:
Time = Distance / Velocity
Given that the distance is 200 km and the velocity is 55 km/hr, you can plug these values into the formula:
Time = 200 km / 55 km/hr
When you divide 200 km by 55 km/hr, you will get the time in hours. To convert it into minutes, you need to multiply it by 60 (since there are 60 minutes in an hour). So the calculation would be:
Time = (200 km / 55 km/hr) * 60 min/hr
Calculating this expression will give you the time in minutes. Finally, to convert it into hours and minutes, you can divide the result by 60 and separate the whole number as hours and the remaining decimals as minutes.
Now let's solve the second question:
Question: An ant carries food at a speed of 1 cm/s. How long will it take the ant to carry a cookie crumb from the kitchen table to the ant hill, a distance of 50m? Express your answer in seconds, minutes, and hours.
First, let's convert the distance from meters to centimeters, since our speed is given in centimeters per second:
Distance = 50m * 100 cm/m
Distance = 5000 cm
Now we can use the formula:
Time = Distance / Velocity
Given that the distance is 5000 cm and the velocity is 1 cm/s, the calculation would be:
Time = 5000 cm / 1 cm/s
Dividing 5000 cm by 1 cm/s will give you the time in seconds. To convert it into minutes and hours, you will divide the result by 60 twice. The whole number will be hours, the remaining decimal will be minutes, and the final decimal will be seconds.
I hope this helps clarify the process for solving these questions!
