How can a biker travel a great distance in a specified time?
• pedal slowly to decrease the speed of the bike
• increase the distance it will cover in the same time allotment
• pedal faster to increase the speed of the bike
• pedal faster to increase the time it will take to cover a distance.
What is the equation to calculate distance?
• distance = speed × time
• distance = time/speed
• distance = speed/time
• distance = speed/distance
Explanation:
To find the distance, just multiply the speed to time.
